This guide helps you to learn more about the each property of ReactiveSearch
API and explains that how to use those properties to build the query for different use-cases.
This guide only contains the fields supported for the Solr search engine.
ReactiveSearch API
request body can be divided into two parts, query
and settings
. The query
key is an Array
of objects where each object represents a ReactiveSearch
query to retrieve the results. Settings(settings
) is an optional key which can be used to control the search experience. Here is an example of the request body of ReactiveSearch
API to get the results for which the title
field matches with iphone
.
{
query: [{
id: "phone-search",
dataField: "title",
size: 10,
value: "iphone"
}],
settings: { // optional
recordAnalytics: true, // to enable the analytics
enableQueryRules: true, // to enable the query rules
}
}
Query parameters
Reactivesearch API supports all the query parameters supported by solr search API.
query
This is a required field
Supported Engines Not dependent on engine, works for all.
id
This is a required field
Supported Engines elasticsearch, mongodb, solr, opensearch
The unique identifier for the query can be referenced in the react
property of other queries. The response of the ReactiveSearch API
is a map of query ids to Elasticsearch
response which means that id
is also useful to retrieve the response for a particular query.

Supported Engines elasticsearch, mongodb, solr, opensearch
Sets the query format, can be or
, and
and date format. Defaults to or
.
-
or
returns all the results matching any of the search query text's parameters. For example, searching for "bat man" with or will return all the results matching either "bat" or "man". -
On the other hand with
and
, only results matching both "bat" and "man" will be returned. It returns the results matching all of the search query text's parameters." -
queryFormat
can be set as Elasticsearch date format forrange
type of queries. It allows Elasticsearch to parse the range values (dates) to a specified format before querying the data. You can find the valid date formats at here.

sortBy
Supported Engines elasticsearch, mongodb, solr, opensearch
This property can be used to sort the results in a particular format. The valid values are:
asc
, sorts the results in ascending order,desc
, sorts the results in descending order,count
, sorts the aggregations bycount
.
Type |
Applicable on query of type |
Required |
---|---|---|
string |
all * |
false |
Note:
Please note that the
count
value can only be applied when the query type is ofterm
. In addition, the pagination property for the query needs to be set tofalse
(default behavior). When pagination istrue
, a composite aggregation is used under the hood, which doesn't support ordering by count.
The sortBy
value by default is set according to the following criterion:
- If field is
_score
, set asdesc
. - If field is anything other than
_score
, set asasc
Following values are supported for this field
asc
, desc
, count
Try out an example in ReactiveSearch Playground
sortField
Supported Engines elasticsearch, solr, opensearch
This field should indicate the field that sort will be applied to. If not passed, then the first entry in the dataField
(if passed as object or array) or the dataField
itself (if passed as string) will be used.
Type |
Applicable on query of type e |
Required |
---|---|---|
String , array of strings , array of string and objects |
all |
false |
The sortField
key accepts different types of values:
1. string
String can be passed where the string is a dataField where sorting is supposed to be done on, following is an example:
{
"sortField": "title"
}
In the above example,
title
is the dataField on which sorting will be done.
In the above example, the sorting method will be the value of sortBy
(if passed) else the default value (which is asc
for any field other than _score
).
2. Array of string
An array of string can also be passed. This can be done in the following way:
{
"sortField": [
"title",
"author",
"price"
]
}
In the above example,
title
,author
andprice
are valid dataFields on which sorting will be done.
In the above example, the sorting order will be based on the value of sortBy
key if passed, or default to asc
order. _score
is a special field to sort by relevance, if specified, it is always sorted in desc
order
3. Array of string / object
sortField
also accepts a combined array where some fields are passed as object. Following is an example:
{
"sortField": [
"title",
{"author": "desc"},
{"price": "asc"}
]
}
In the above example, the sort order for title
field will be asc
(i.e. ascending). For the other fields, it will be as passed. The object should have the dataField as the key and the sort order as its value, only asc
or desc
are valid values here.
value
Supported Engines elasticsearch, mongodb, solr, opensearch
Represents the value for a particular query type, each kind of query has the different type of value format.
Type |

You can check the value
format for different type
of queries:
format for search
and suggestion
type

or int
.
Example Playground:

type
The value can be a string
or Array<string>
.
Example Playground:
format for range
type
The value should be an Object
in the following shape:
{
"start": int | double | date, // optional
"end": int | double | date, // optional
"boost": int
}
Note:
Either
start
orend
property must present in the value.
Example Playground:
format for geo
type
The value should be an Object
in the following shape:
{
// The following properties can be used to get the results within a particular distance and location.
"distance": int,
"location": string, // must be in `{lat}, {lon}` format
"unit": string,
// The following properties can be used to get the results for a particular geo bounding box.
"geoBoundingBox": {
topLeft: string, // required, must be in `{lat}, {lon}` format
bottomRight: string, // required, must be in `{lat}, {lon}` format
}
}
Note: The
geoBoundingBox
property can not be used withlocation
property, if both are defined thangeoBoundingBox
value will be ignored.
The below example represents a geo distance query:
{
"id": "distance_filter",
"type": "geo",
"dataField": ["location"],
"value": {
"distance":10,
"location":"22.3184816, 73.17065699999999",
"unit": "mi/yd/ft/km/m/cm/mm/nmi"
}
}
The below example represents a geo bounding box query:
{
"id": "bounding_box_filter",
"type": "geo",
"dataField": ["location"],
"value": {
"geoBoundingBox": {
"topLeft": "40.73, -74.1",
"bottomRight": "40.01, -71.12",
}
}
}

defaultQuery
Supported Engines elasticsearch, mongodb, solr, opensearch
This property is useful to customize the source query, as defined in Elasticsearch Query DSL. It is different from the customQuery in a way that it doesn't get leaked to other queries(dependent queries by react
prop) and only modifies the query for which it has been applied.
You can read more about the defaultQuery
usage over here.

property, as defined in Elasticsearch Query DSL. You can read more about the customQuery
usage over here.
Note:
It'll not affect that particular query for which it has been defined, it'll only affect the query for dependent queries. If you want to customize the source query then use the defaultQuery property instead.

execute
Supported Engines elasticsearch, mongodb, solr, opensearch
Sometimes it may require that you want to apply some query for results with the help of react
property but want to avoid any un-necessary query execution for the performance reasons. If you set execute
to false
for a particular query then you can use it with react
prop without executing it.
For example, consider a scenario where we want to filter the search query by some range. To implement it with RS API we need to define two queries(search & range type). Since you defined the two queries then by default both queries will get executed, however you can avoid this by setting execute
to false
for the range query.

As of now, the backend
field supports the following values:
elasticsearch
: ElasticSearchopensearch
: OpenSearch
where elasticsearch
is the default value.
This field is necessary if backend is OpenSearch and the kNN reordering of scripts are to be used.
Following example indicates how to use this field to use kNN reordering with OpenSearch as backend:
{
"query": [
{
"value": "sudoku",
"vectorDataField": "name_vector",
"queryVector": [1.0, -0.2],
}
],

This fields indicates which values should be included in the terms aggregation (if done so). Only applied for term
type of queries.
This should be of type array of strings:
{

}]
}
NOTE: The string can be a regex as well but only for ElasticSearch backend, not Solr.
ElasticSearch
For ElasticSearch this maps to the include
field inside the term
query.
Solr
For Solr, this maps to the facet.contains
field.
