[[index-phrases]]
=== `index_phrases`

If enabled, two-term word combinations ('shingles') are indexed into a separate
field.  This allows exact phrase queries (no slop) to run more efficiently, at the expense
of a larger index.  Note that this works best when stopwords are not removed,
as phrases containing stopwords will not use the subsidiary field and will fall
back to a standard phrase query.  Accepts `true` or `false` (default).
Add pointer to the index-phrases option in shingle filter docs (#35771) We should be discouraging the use of shingle filters and instead pointing users to the index-phrases parameter on text fields. 2018-11-21 10:27:11 -05:00			`[[index-phrases]]`
Improve docs for index_prefixes option (#35778) This commit moves the documentation and examples for the `index_prefixes` option on text fields to its own file, to bring it in line with other mapping parameters, and expands a bit on both. 2018-11-22 04:20:46 -05:00			=== `index_phrases`
