Run multiple templated searches | Elasticsearch Serverless API documentation

Run multiple templated searches Added in 5.0.0

POST /{index}/_msearch/template

Run multiple templated searches with a single request. If you are providing a text file or text input to curl, use the --data-binary flag instead of -d to preserve newlines. For example:

$ cat requests
{ "index": "my-index" }
{ "id": "my-search-template", "params": { "query_string": "hello world", "from": 0, "size": 10 }}
{ "index": "my-other-index" }
{ "id": "my-other-search-template", "params": { "query_type": "match_all" }}

$ curl -H "Content-Type: application/x-ndjson" -XGET localhost:9200/_msearch/template --data-binary "@requests"; echo

explain boolean

If true, the request returns detailed information about score computation as part of a hit.

ext object

Configuration of search extensions defined by Elasticsearch plugins.

Hide ext attribute Show ext attribute object

* object Additional properties

from number

The starting document offset, which must be non-negative. By default, you cannot page through more than 10,000 hits using the from and size parameters. To page through more hits, use the search_after parameter.

highlight object

Hide highlight attributes Show highlight attributes object

type

boundary_chars string

A string that contains each boundary character.

boundary_max_scan number

How far to scan for boundary characters.

boundary_scanner string

Values are chars, sentence, or word.

boundary_scanner_locale string

Controls which locale is used to search for sentence and word boundaries. This parameter takes a form of a language tag, for example: "en-US", "fr-FR", "ja-JP".

force_source boolean Deprecated

fragmenter string

Values are simple or span.

fragment_size number

The size of the highlighted fragment in characters.

highlight_filter boolean

highlight_query object

An Elasticsearch Query DSL (Domain Specific Language) object that defines a query.

max_fragment_length number

max_analyzed_offset number

If set to a non-negative value, highlighting stops at this defined maximum limit. The rest of the text is not processed, thus not highlighted and no error is returned The max_analyzed_offset query setting does not override the index.highlight.max_analyzed_offset setting, which prevails when it’s set to lower value than the query setting.

no_match_size number

The amount of text you want to return from the beginning of the field if there are no matching fragments to highlight.

number_of_fragments number

The maximum number of fragments to return. If the number of fragments is set to 0, no fragments are returned. Instead, the entire field contents are highlighted and returned. This can be handy when you need to highlight short texts such as a title or address, but fragmentation is not required. If number_of_fragments is 0, fragment_size is ignored.

options object

order string

Value is score.

phrase_limit number

Controls the number of matching phrases in a document that are considered. Prevents the fvh highlighter from analyzing too many phrases and consuming too much memory. When using matched_fields, phrase_limit phrases per matched field are considered. Raising the limit increases query time and consumes more memory. Only supported by the fvh highlighter.

post_tags array[string]

Use in conjunction with pre_tags to define the HTML tags to use for the highlighted text. By default, highlighted text is wrapped in <em> and </em> tags.

pre_tags array[string]

Use in conjunction with post_tags to define the HTML tags to use for the highlighted text. By default, highlighted text is wrapped in <em> and </em> tags.

require_field_match boolean

By default, only fields that contains a query match are highlighted. Set to false to highlight all fields.

tags_schema string

Value is styled.

encoder string

Values are default or html.

fields object Required

track_total_hits boolean | number

Number of hits matching the query to count accurately. If true, the exact number of hits is returned at the cost of some performance. If false, the response does not include the total number of hits matching the query. Defaults to 10,000 hits.

indices_boost array[object]

Boost the _score of documents from specified indices. The boost value is the factor by which scores are multiplied. A boost value greater than 1.0 increases the score. A boost value between 0 and 1.0 decreases the score.

suggest object

Hide suggest attribute Show suggest attribute object

text string

Global suggest text, to avoid repetition when the same text is used in several suggesters

terminate_after number

The maximum number of documents to collect for each shard. If a query reaches this limit, Elasticsearch terminates the query early. Elasticsearch collects documents before sorting.

IMPORTANT: Use with caution. Elasticsearch applies this property to each shard handling the request. When possible, let Elasticsearch perform early termination automatically. Avoid specifying this property for requests that target data streams with backing indices across multiple data tiers.

If set to 0 (default), the query does not terminate early.

timeout string

The period of time to wait for a response from each shard. If no response is received before the timeout expires, the request fails and returns an error. Defaults to no timeout.

track_scores boolean

If true, calculate and return document scores, even if the scores are not used for sorting.

version boolean

If true, the request returns the document version as part of a hit.

seq_no_primary_term boolean

If true, the request returns sequence number and primary term of the last modification of each hit.
