<<query-dsl-distance-feature-query,`distance_feature` query>>::
|
|
A query that computes scores based on the dynamically computed distances
|
|
between the origin and documents' `date`, `date_nanos`, and `geo_point` fields.
|
|
It is able to efficiently skip non-competitive hits.
|
|
|
|
<<query-dsl-mlt-query,`more_like_this` query>>::
|
|
This query finds documents which are similar to the specified text, document,
|
|
or collection of documents.
|
|
|
|
<<query-dsl-percolate-query,`percolate` query>>::
|
|
This query finds queries that are stored as documents that match with
|
|
the specified document.
|
|
|
|
<<query-dsl-knn-query,`knn` query>>::
|
|
A query that finds the _k_ nearest vectors to a query
|
|
vector, as measured by a similarity metric.
|
|
|
|
<<query-dsl-rank-feature-query,`rank_feature` query>>::
|
|
A query that computes scores based on the values of numeric features and is
|
|
able to efficiently skip non-competitive hits.
|
|
|
|
<<query-dsl-script-query,`script` query>>::
|
|
This query allows a script to act as a filter. Also see the

|
<<query-dsl-script-score-query,`script_score` query>>::
|
|
A query that allows to modify the score of a sub-query with a script.
|
|
|
|
<<query-dsl-semantic-query,`semantic` query>>::
|
|
A query that allows you to perform semantic search.
|
|
|
|
<<query-dsl-wrapper-query,`wrapper` query>>::
|
|
A query that accepts other queries as json or yaml string.
|

|
|
<<query-dsl-pinned-query,`pinned` query>>::
|
|
A query that promotes selected documents over others matching a given query.
|
