This part of the dialog lets you constructc 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.
