PhraseQuery suffices for the stated requirement of boosting when query terms
are closer. A common technique is to incorporate a PhraseQuery with a large
slop factor of the query terms into the query automatically, which implicitly
boosts matching documents when the query terms are closer. A SpanNearQuery
would work too, but a PhraseQuery might be easier to incorporate and will be
faster performing.
