Faster phrase queries with index_phrases
edit
The text
field has an index_phrases
option that
indexes 2-shingles and is automatically leveraged by query parsers to run phrase
queries that don’t have a slop. If your use-case involves running lots of phrase
queries, this can speed up queries significantly.
