Nested expressions searching in Help

Nested expressions enable you to create complex searches for information in the Help file.

For example, control AND ((active OR dde) NEAR window) finds topics containing the word control along with the words active and window close together or containing control along with the words dde and window close together.

The basic rules for searching help topics using nested expressions are:

• You can use parentheses to nest expressions within a query. The expressions in parentheses are evaluated before the rest of the query
• If a query does not contain a nested expression, it is evaluated from left to right.

  For example, Control not active OR dde finds topics containing the word control without the word active or topics containing the word dde.

  On the other hand, control not (active OR dde) finds topics containing the word control without either of the words active or dde.

• You cannot nest expressions more than five levels deep
