Tip 1:
Use quotation marks for exact phrases. For example, "Sydney Opera House" with the quotations included will only return pages that have the Sydney Opera House listed. Without the quotation marks, your search results will show every page that has the word Sydney, the word opera and the word house listed.

Tip 2:
Use + and - before your keywords to match only pages with (or without) the words in them. For example, "+tours -air" will match all pages with tours but not air listed.
