Wildcard and phrase Help searches

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.

If you search for a single word like "select", you will also find its grammatical variations, such as "selector" and "selection."

If you search for "new operator" you will find 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.

If you search for "esc*" you will find topics that contain the terms "ESC," "escape," "escalation," and so on. The asterisk cannot be the only character in the term.

If you search for "80?86" you will find topics that contain the terms "80186," "80286," "80386," and so on. The question mark cannot be the only character in the term.


Note:

Select the Match similar words check box to include minor grammatical variations for the phrase you search.
