bool TermList::uniform_prefixes [private] |
Keep track of whether the terms added all have the same list of prefixes.
If so, we'll build a set of phrases, one using each prefix. This works around the limitation that a phrase cannot have multiple components which are "OR" combinations of terms, but is also probably what users expect: ie, if a user specifies a phrase in a field, and that field maps to multiple prefixes, the user probably wants a phrase returned with all terms having one of those prefixes, rather than a phrase comprised of terms with differing prefixes.
Definition at line 1209 of file queryparser_internal.cc.
list<string> TermList::prefixes [private] |
The list of prefixes of the terms added.
This will be empty if the terms have different prefixes.
