Глава 80. The Full Text Search

Searching for words or phrases

You can search for words or phrases and use wildcard expressions.

Wildcard expressions allow you to search for one or more characters

using a question mark or asterisk. The table below describes the

results of these different kinds of searches.

Таблица 80-1. Word and phrase searches

Search for

Example

Results

A single word

select

Topics that contain the word "select". (You will also find its grammatical variations, such as "selector" and "selection".)

A phrase

"new operator" or new operator

Topics that contain the literal phrase "new operator" and all its grammatical variations.

Without the quotation marks, the query is equivalent to specifying "new AND operator," which

will find topics containing both of the individual words, instead of the phrase.

Wildcard expressions

esc* or HT??

Results for the first example include topics that contain the terms "ESC",

"escape", "escalation", and so on. The asterisk cannot be the only

character in the term.

Results for the second example include topics that contain the terms "HTTP",

"HTML" and so on. The question mark cannot be the only character in the

term.

Замечание:

Select the Match similar words check box to include minor grammatical variations

for the phrase you search. This feature only locates variations of the word with

common suffixes. For example, a search on the word "add" will find "added," but

it will not find "additive". This option is independent of other options or syntax.

If you do a titles-only search, variations in titles will be matched. If you use

quotes (or any other query operator) any variation of the word can appear; for

example, "stemmed search" will also match "stemming search".
