Phrases searches. A phrase can be
looked for by enclosing a number of terms in double
quotes. Example: "user manual" will look only
for occurrences of user immediately followed
by manual. You can use
the "Phrase" field of the advanced search
dialog to the same effect. Phrases can be entered along simple
terms in all simple or advanced search entry fields,
except "Phrase".
Proximity searches. A proximity search differs from a phrase search in that it does not impose an order on the terms. Proximity searches can be entered by specifying the "Proximity" type in the advanced search, or by postfixing a phrase search with a 'p'. Example: "user manual"p would also match "manual user". Also see the modifier section from the query language documentation.
AutoPhrases. This option can be set in the preferences dialog. If it is
set, a phrase will be automatically built and added to simple
searches when looking for Any terms. This
will not change radically the results, but will give a relevance
boost to the results where the search terms appear as a
phrase. E.g.: searching for virtual reality
will still find all documents where either
virtual or reality or
both appear, but those which contain
virtual reality should appear sooner in the
list.
Phrase searches can slow down a query if most of the
terms in the phrase are common. If
the autophrase option is on, very common
terms will be removed from the automatically constructed
phrase. The removal threshold can be adjusted from the search
preferences.
Phrases and abbreviations. Dotted abbreviations like
I.B.M. are also automatically indexed as a
word without the dots: IBM. Searching for
the word inside a phrase (e.g.: "the IBM
company") will only match the dotted abrreviation
if you increase the phrase slack (using the advanced search
panel control, or the o query language
modifier). Literal occurrences of the word will be matched
normally.
