Working with phrases and proximity

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. Ie: 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 (ie: "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.
