# Term-level queries
|
|
|
|
Term-level queries search an index for documents that contain an exact search term. Documents returned by a term-level query are not sorted by their relevance scores.
|
|
|
|
When working with text data, use term-level queries for fields mapped as `keyword` only.
|
|
|
|
Term-level queries are not suited for searching analyzed text fields. To return analyzed fields, use a [full-text query]({{site.url}}{{site.baseurl}}/opensearch/query-dsl/full-text/).
|
|
|
|
## Term-level query types
|
|
|
|
The following table lists all term-level query types.
|
|
|
|
Query type | Description
|
|
:--- | :---
|
|
[`term`]({{site.url}}{{site.baseurl}}/query-dsl/term/term/) | Searches for documents containing an exact term in a specific field.
|
|
[`terms`]({{site.url}}{{site.baseurl}}/query-dsl/term/terms/) | Searches for documents containing one or more terms in a specific field.
|
|
[`terms_set`]({{site.url}}{{site.baseurl}}/query-dsl/term/terms-set/) | Searches for documents that match a minimum number of terms in a specific field.
|
|
[`ids`]({{site.url}}{{site.baseurl}}/query-dsl/term/ids/) | Searches for documents by document ID.
|
|
[`range`]({{site.url}}{{site.baseurl}}/query-dsl/term/range/) | Searches for documents with field values in a specific range.
|
|
[`prefix`]({{site.url}}{{site.baseurl}}/query-dsl/term/prefix/) | Searches for documents containing terms that begin with a specific prefix.
|
|
[`exists`]({{site.url}}{{site.baseurl}}/query-dsl/term/exists/) | Searches for documents with any indexed value in a specific field.
|
|
[`fuzzy`]({{site.url}}{{site.baseurl}}/query-dsl/term/fuzzy/) | Searches for documents containing terms that are similar to the search term within the maximum allowed [Levenshtein distance](https://en.wikipedia.org/wiki/Levenshtein_distance). The Levenshtein distance measures the number of one-character changes needed to change one term to another term.
|
|
[`wildcard`]({{site.url}}{{site.baseurl}}/query-dsl/term/wildcard/) | Searches for documents containing terms that match a wildcard pattern.
|
|
[`regexp`]({{site.url}}{{site.baseurl}}/query-dsl/term/regexp/) | Searches for documents containing terms that match a regular expression. |
