Nesting enables you to create complex search queries by combining search expressions. To use nested search expressions when searching Help topics, keep in mind the following guidelines:
- Use parentheses to nest expressions within a search query. The expressions in parentheses are evaluated before the rest of the query. For example, the query "software NOT (metering OR database)" finds topics containing the word "software," without either of the words "metering" or "database."
- If a query does not contain a nested element, it is evaluated from left to right. In this case, the query "software NOT metering OR database" finds topics containing the word "software" without the word "metering," or topics containing the word "database."
- The complex query "software AND ((metering OR database) NEAR role)" finds topics that contain the word "software," along with the words "metering" and "role" that are close together (within eight words), or that contain the word "software," along with the words "database" and "role" that are close together.
Note
You can nest expressions only five levels deep.
