Specifying `index_phrases: true` on a text field mapping will add a subsidiary [field]._index_phrase field, indexing two-term shingles from the parent field. The parent analysis chain is re-used, wrapped with a FixedShingleFilter. At query time, if a phrase match query is executed, the mapping will redirect it to run against the subsidiary field. This should trade faster phrase querying for a larger index and longer indexing times. Relates to #27049 |
