This part of the dialog lets you construct a query by combining multiple clauses of different types. Each entry field is configurable for the following modes:
All terms.
Any term.
None of the terms.
Phrase (exact terms in order within an adjustable window).
Proximity (terms in any order within an adjustable window).
Filename search.
Additional entry fields can be created by clicking the Add clause button.
When searching, the non-empty clauses will be combined either with an AND or an OR conjunction, depending on the choice made on the left (All clauses or Any clause).
Entries of all types except "Phrase" and "Near" accept a mix of single words and phrases enclosed in double quotes. Stemming and wildcard expansion will be performed as for simple search.
Phrases and Proximity searches. These two clauses work in similar ways, with the difference
that proximity searches do not impose an order on the words. In
both cases, an adjustable number (slack) of non-matched words may
be accepted between the searched ones (use the counter on the
left to adjust this count). For phrases, the default count is
zero (exact match). For proximity it is ten (meaning that two
search terms, would be matched if found within a window of twelve
words). Examples: a phrase search for
quick fox with a slack of 0 will match
quick fox but not
quick brown fox. With
a slack of 1 it will match the latter, but not
fox quick. A proximity search for
quick fox with the default slack will
match the latter, and also
a fox is a cunning and quick animal.
