.Overview "Retrieval/Phrases"
The most comnonly used lq-text functions are in this category (and also
in the Database/Defaults section, strictly speaking).
.P
Functions in this category deal with converting a string into an internal
data structure representing a phrase, and getting a list of matches for that
phrase.
.P
The intermediate step involving the internal data structure allows clients
to determine useful information, such as how many words were recognised
in the phrase, without the overhead of doing the actual match.
