Term query elasticsearch

The Open Distro project is archived. Open Distro development has moved to OpenSearch. The Open Distro plugins will continue to work with legacy versions of Elasticsearch OSS, term query elasticsearch, but we recommend upgrading to OpenSearch to take advantage of the latest features and improvements. Elasticsearch supports two types of queries when you search for data: term-level queries and full-text queries.

Returns documents that contain an exact term in a provided field. You can use the term query to find documents based on a precise value such as a price, a product ID, or a username. Avoid using the term query for text fields. By default, Elasticsearch changes the values of text fields as part of analysis. This can make finding exact matches for text field values difficult.

Term query elasticsearch

Returns documents that contain one or more exact terms in a provided field. The terms query is the same as the term query , except you can search for multiple values. The following search returns documents where the user. The value of this parameter is an array of terms you wish to find in the provided field.

Optional, float Floating point number used to decrease or increase the relevance scores of a query. Defaults to 1.

First it searches for documents which match the more important terms. The Open Distro plugins will continue to work with legacy versions of Elasticsearch OSS, term query elasticsearch, but we recommend upgrading to OpenSearch to take advantage of the latest features and improvements.

Use Match instead, which skips blocks of documents efficiently, without any configuration, provided that the total number of hits is not tracked. The common terms query is a modern alternative to stopwords which improves the precision and recall of search results by taking stopwords into account , without sacrificing performance. Every term in a query has a cost. A search for "The brown fox" requires three term queries, one for each of "the" , "brown" and "fox" , all of which are executed against all documents in the index. The query for "the" is likely to match many documents and thus has a much smaller impact on relevance than the other two terms. Previously, the solution to this problem was to ignore terms with high frequency. By treating "the" as a stopword , we reduce the index size and reduce the number of term queries that need to be executed.
