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.
Term-level query types
The following table lists all term-level query types.
| Query type | Description |
|---|---|
term | Searches for documents containing an exact term in a specific field. |
terms | Searches for documents containing one or more terms in a specific field. |
terms_set | Searches for documents that match a minimum number of terms in a specific field. |
ids | Searches for documents by document ID. |
range | Searches for documents with field values in a specific range. |
prefix | Searches for documents containing terms that begin with a specific prefix. |
exists | Searches for documents with any indexed value in a specific field. |
fuzzy | Searches for documents containing terms that are similar to the search term within the maximum allowed Levenshtein distance. The Levenshtein distance measures the number of one-character changes needed to change one term to another term. |

regexp | Searches for documents containing terms that match a regular expression. |
