By default, most popular search engines try to locate pages that have
exact matches for all of the words entered in your search
query. If that fails, they then try to locate pages that contain
any of the words in your search query.

There are several standard methods that you can use to modify this
default search engine behavior.
Phrase Search – To match an exact phrase, use quotes around
the phrase, for example "business news".
+ and - Qualifiers – If you prepend a word with +, that
word must be on the page. If you prepend a word with -, that
word must not be on the page, for example +always -never.
* Wildcard – If a query word ends with *, all words on a
page that start the same way as that query word will match, for example
? Wildcard – If a query word contains ?, any character
will match that position, for example b?g.
Boolean Search – You can use the boolean operators AND,
OR, and NOT in your search, for example contact AND
us or about AND us. These operators must be capitalized,
