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.
These two clauses look for a group of terms in
specified relative positions. They differ in the sense that the order of input terms
is significant for phrase searches, but not
for proximity searches. The latter 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. For phrase searches, the
default count is zero (exact match). For proximity searches 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.
The slack can be adjusted with the counter to the left of the input area
