CategorySearch
creates a category based data search UI component with an autosuggest functionality. It is used for applying full-text search across one or more fields.
Example uses:
- Searching for a rental listing by its
name
ordescription
field. - Creating an e-commerce search box for finding products by their listing properties.

Props
componentId
Type | Optional |
---|---|
String |
No |
unique identifier of the component, can be referenced in other components' react
prop.
compoundClause
Type | Optional |
---|---|
String |
Yes |
Configure whether the DSL query is generated with the compound clause of must
or filter
. If nothing is passed the default is to use must
. Setting the compound clause to filter allows search engine to cache and allows for higher throughput in cases where scoring isn’t relevant (e.g. term, geo or range type of queries that act as filters on the data)
This property only has an effect when the search engine is either elasticsearch or opensearch.
Note:
compoundClause
is supported with v8.16.0 (server) as well as with serverless search.
endpoint
Type | Optional |
---|---|
Object |
Yes |
endpoint prop provides the ability to query a user-defined backend service for this component, overriding the data endpoint configured in the ReactiveBase component. Works only when enableAppbase
is true
.
Accepts the following properties:
- url
String
[Required] URL where the data cluster is hosted. - headers
Object
[optional]
set custom headers to be sent with each server request as key/value pairs. - method
String
[optional]
set method of the API request. - body
Object
[optional]
request body of the API request. When body isn't set and method is POST, the request body is set based on the component's configured props.
- Overrides the endpoint property defined in ReactiveBase.
- If required, use
transformResponse
prop to transform response in component-consumable format.
dataField
Type | Optional |
---|---|
string | Array<string | DataField*> |
No |
index field(s) to be connected to the component’s UI view. CategorySearch accepts an Array
in addition to string
, which is useful for searching across multiple fields with or without field weights.
Field weights allow weighted search for the index fields. A higher number implies a higher relevance weight for the corresponding field in the search results.
You can define the dataField
property as an array of objects of the DataField
type to set the field weights.
The DataField
type has the following shape:
type DataField = {
field: string;
weight: number;
};
database field(s) to be queried against. Accepts an Array in addition to String, useful for applying search across multiple fields. Check examples at here.
Note:
- This prop is optional only when
enableAppbase
prop is set totrue
inReactiveBase
component.- The
dataField
property asDataField
object is only available for ReactiveSearch version >=v3.21.0
and Appbase versionv7.47.0
.
size
Type | Optional |
---|---|
Number |
Yes |
number of suggestions to show. Defaults to 10
.
aggregationField
Type | Optional |
---|---|
String |
Yes |
One of the most important use-cases this enables is showing DISTINCT
results (useful when you are dealing with sessions, events and logs type data). It utilizes composite aggregations
which are newly introduced in ES v6 and offer vast performance benefits over a traditional terms aggregation.
You can read more about it over here. You can access aggregationData
using render prop as shown:
<CategorySearch
aggregationField="original_title.keyword"
render={({aggregationData}) => {...}}
/>
If you are using an app with elastic search version less than 6, then defining this prop will result in error and you need to handle it manually using renderError prop.
It is possible to override this query by providing
defaultQuery
orcustomQuery
.
Note: This prop has been marked as deprecated starting v3.18.0. Please use the
distinctField
prop instead.
aggregationSize
To set the number of buckets to be returned by aggregations.
Note: This is a new feature and only available for appbase versions >= 7.41.0.
nestedField
Type | Optional |
---|---|
String |
Yes |
Set the path of the nested
type under which the dataField
is present. Only applicable only when the field(s) specified in the dataField
is(are) present under a nested
type mapping.
categoryField
Type | Optional |
---|---|
String |
Yes |
data field which has the category values mapped.
title
Type | Optional |
---|---|
String or JSX |
Yes |
Sets the title of the component to be shown in the UI.
defaultValue
Type | Optional |
---|---|
Object |
Yes |
set the initial search query text on mount & the category.
value
Type | Optional |
---|---|
Object |
Yes |
sets the current value of the component. It sets the search query text & the category (on mount and on update). Use this prop in conjunction with the onChange
props. Usage:
<CategorySearch
{...searchProps}
value={{
term: 'Harry',
category: '*',
}}
/>
onChange
Type | Optional |
---|---|
function |
Yes |
is a callback function which accepts component's current value as a parameter. It is called when you are using the value
prop and the component's value changes. This prop is used to implement the controlled component behavior.
<CategorySearch
value={this.state.value}
onChange={(value, triggerQuery, event) => {
this.setState({ value }, () => triggerQuery());
}}
/>
Note:
If you're using the controlled behavior than it's your responsibility to call the
triggerQuery
method to update the query i.e execute the search query and update the query results in connected components byreact
prop. It is not mandatory to call thetriggerQuery
inonChange
you can also call it in other input handlers likeonBlur
oronKeyPress
.
enableSynonyms
Type | Optional |
---|---|
bool |
Yes |
Defaults to true
, can be used to disable/enable
the synonyms behavior for the search query. Read more about it here
Note:
This property only works with ReactiveSearch API i.e when
enableAppbase
is set totrue
inReactiveBase
component.
enableQuerySuggestions
Type | Optional |
---|---|
bool |
Yes |
This prop has been marked as deprecated starting v3.12.6
. Please use the enablePopularSuggestions
prop instead.
enablePopularSuggestions
Type | Optional |
---|---|
bool |
Yes |
Defaults to false
. When enabled, it can be useful to curate search suggestions based on actual search queries that your users are making. Read more about it over here.
Note:
Popular Suggestions only work when
enableAppbase
prop istrue
.
enableRecentSearches
Type | Optional |
---|---|
Boolean |
Yes |
Defaults to false
. If set to true
then users will see the top recent searches as the default suggestions. Appbase.io recommends defining a unique id(userId
property) in appbaseConfig
prop for each user to personalize the recent searches.
Note: Please note that this feature only works when
recordAnalytics
is set totrue
inappbaseConfig
.
enablePredictiveSuggestions
Type | Optional |
---|---|
bool |
Yes |
Defaults to false
. When set to true
, it predicts the next relevant words from a field's value based on the search query typed by the user. When set to false
(default), the entire field's value would be displayed. This may not be desirable for long-form fields (where average words per field value is greater than 4 and may not fit in a single line).
downShiftProps
Type | Optional |
---|---|
Object |
Yes |
allow passing props directly to the underlying Downshift
component. You can read more about Downshift props here.

Type | Optional |
---|---|
Array |
Yes |
set the search weight for the database fields, useful when dataField is an Array of more than one field. This prop accepts an array of numbers. A higher number implies a higher relevance weight for the corresponding field in the search results.
Note: The
fieldWeights
property has been marked as deprecated in v3.21.0 of ReactiveSearch and v7.47.0 of appbase.io and would be removed in the next major release. We recommend you to use the dataField property to define the weights.

Show 1 suggestion per document. If set to false
multiple suggestions may show up for the same document as searched value might appear in multiple fields of the same document, this is true only if you have configured multiple fields in dataField
prop. Defaults to true
.
Example if you have showDistinctSuggestions
is set to false
and have following configurations
// Your document:
{
"name": "Warn",
"address": "Washington"
}
// Component:
<DataSearch dataField=['name', 'address'] .../>

sort: [{ timestamp: 'asc' }],
},
max_concurrent_group_searches: 4,
}}
/>
> Note: In order to use the `distinctField` and `distinctFieldConfig` props, the `enableAppbase` prop must be set to true in `ReactiveBase`.
Demo
Styles
CategorySearch
component supports an innerClass
prop to provide styles to the sub-components of CategorySearch. These are the supported keys:
title
input
list
recent-search-icon
popular-search-icon
Read more about it here.
Extending
CategorySearch
component can be extended to:
- customize the look and feel with
className
,style
, - update the underlying DB query with
customQuery
, - connect with external interfaces using
beforeValueChange
,onValueChange
,onValueSelected
andonQueryChange
, - specify how search suggestions should be filtered using
react
prop, - use your own function to render suggestions using
parseSuggestion
prop. It expects an object back for eachsuggestion
having keyslabel
andvalue
. The query is run against thevalue
key andlabel
is used for rendering the suggestions.label
can be eitherString
or JSX. For example,
<CategorySearch
...
parseSuggestion={(suggestion) => ({
label: (
<div>
{suggestion._source.original_title} by
<span style={{ color: 'dodgerblue', marginLeft: 5 }}>
{suggestion._source.authors}
</span>
</div>
),
value: suggestion._source.original_title,
source: suggestion._source // for onValueSelected to work with parseSuggestion
})}
/>
- it's also possible to take control of rendering individual suggestions with
parseSuggestion
prop or the entire suggestions rendering using therender
prop. Check the custom suggestions recipe for more info.
-
add the following synthetic events to the underlying
input
element:- onBlur
- onFocus
- onKeyPress
- onKeyDown
- onKeyUp
- autoFocus
Note:
- All these events accepts the
triggerQuery
as a second parameter which can be used to trigger theCategorySearch
query with the current selected value (useful to customize the search query execution). - There is a known issue with
onKeyPress
whenautosuggest
is set to true. It is recommended to useonKeyDown
for the consistency.
<CategorySearch
...
className="custom-class"
style={{"paddingBottom": "10px"}}
customQuery={
function(value, props, category) {
return {
query: {
match: {
data_field: "this is a test"
}
}
}
}
}
beforeValueChange={
function(value) {
// called before the value is set
// returns a promise
return new Promise((resolve, reject) => {
// update state or component props
resolve()
// or reject()
})
}
}
onValueChange={
function(value) {
console.log("current value: ", value)
// set the state
// use the value with other js code
}
}
onValueSelected={
function(value, category, cause, source) {
console.log("current value and category: ", value, category)
}
}
onQueryChange={
function(prevQuery, nextQuery) {
// use the query with other js code

console.log('nextQuery', nextQuery);
}
}
// specify how and which suggestions are filtered using `react` prop.
react={
"and": ["pricingFilter", "dateFilter"],
"or": ["searchFilter"]
}
/>
className
Type | Optional |
---|---|
String |
Yes |
CSS class to be injected on the component container.
style
Type | Optional |
---|---|
Object |
Yes |
CSS styles to be applied to the CategorySearch component.
customQuery
Type | Optional |
---|---|
Function |
Yes |
takes value, props and category as parameters and returns the data query to be applied to the component, as defined in Elasticsearch Query DSL.
Note:
customQuery is called on value changes in the CategorySearch component as long as the component is a part of react
dependency of at least one other component.
defaultQuery
Type | Optional |
---|---|
Function |
Yes |
takes value, props and category as parameters and returns the data query to be applied to the source component, as defined in Elasticsearch Query DSL, which doesn't get leaked to other components. In simple words, defaultQuery
prop allows you to modify the query to render the suggestions when autoSuggest
is enabled.
Read more about it here.
beforeValueChange
Type | Optional |
---|---|
Function |
Yes |
is a callback function which accepts component's future value as a parameter and returns a promise. It is called everytime before a component's value changes. The promise, if and when resolved, triggers the execution of the component's query and if rejected, kills the query execution. This method can act as a gatekeeper for query execution, since it only executes the query after the provided promise has been resolved.
Note:
If you're using Reactivesearch version >=
3.3.7
,beforeValueChange
can also be defined as a synchronous function.value
is updated by default, unless you throw anError
to reject the update. For example:

onValueChange
Type | Optional |
---|---|
Function |
Yes |
is a callback function which accepts component's current value as a parameter. It is called everytime the component's value changes. This prop is handy in cases where you want to generate a side-effect on value selection. For example: You want to show a pop-up modal with the valid discount coupon code when a user searches for a product in a CategorySearch.
onValueSelected
Type | Optional |
---|---|
Function |
Yes |
is called with the value and the category selected via user interaction. If the search was performed by selecting the 'in all categories' suggestion, category is received as *
. If it was performed for one of the categorized suggestion, the category
is received. In other cases (either searching without selecting a suggestion or picking an uncategorized suggestion), category
is received as null
. It works only with autosuggest
and is called whenever a suggestion is selected or a search is performed by pressing enter key. It also passes the cause
of action and the source
object if the cause of action was 'SUGGESTION_SELECT'
. The source would be null
if a category based suggestion was selected. The possible causes are:
'SUGGESTION_SELECT'
'ENTER_PRESS'
'CLEAR_VALUE'
'SEARCH_ICON_CLICK'
onQueryChange
Type | Optional |
---|---|
Function |
Yes |
