position_increment_gap
editposition_increment_gap
editAnalyzed text fields take term positions
into account, in order to be able to support
proximity or phrase queries.
When indexing text fields with multiple values a "fake" gap is added between
the values to prevent most phrase queries from matching across the values. The
size of this gap is configured using position_increment_gap
and defaults to
100
.
For example:
PUT my-index-000001/_doc/1 { "names": [ "John Abraham", "Lincoln Smith"] } GET my-index-000001/_search { "query": { "match_phrase": { "names": { "query": "Abraham Lincoln" } } } } GET my-index-000001/_search { "query": { "match_phrase": { "names": { "query": "Abraham Lincoln", "slop": 101 } } } }
This phrase query doesn’t match our document which is totally expected. |

This phrase query matches our document, even though |
The position_increment_gap
can be specified in the mapping. For instance:
