Use quotes to find an exact phrase, for example: "query plan"

Boolean operators and parentheses are allowed. For example: "XML schema" AND (source OR target) NOT dtd. Note: the operator AND is implied when no other Boolean operator is used.

Use the asterisk (*) as a suffix wildcard character in keywords. For example, admin* will find documents with keywords such as administration or administrator.

Use the NEAR operator to find keywords that appear near to each other. For example, scope NEAR target will find documents with words scope and target appearing within roughly 50 words of one another.

For more precision than the NEAR operator, use the w/number operator. For example, query w/5 cache will find documents where query and cache are within 5 words of each other (ignoring common words like the, that, of, and so on).
