phrase search
The search engine supports three types of phrase search.
To match an exact phrase, use quotes around the phrase
Example: "free search engine"

To match a near (within a couple of words) phrase, use square brackets [around the words]
Example: [free search engine]

To match a far (within several words) phrase, use braces { around the words }
Example: {free search engine}

+ and - qualifiers
If you prepend a word with + that word is required to be on the page.
If you prepend a word with - that word is required to not be on the page.
Example: +always -never

* wildcard
If a query word ends with a * all words on a page which start the same way as that query word will match.
Example: gift*

? wildcard
If a query word contains a ? any character will match that position.
Example: b?g

boolean search
You can use the following boolean operators in your search: AND, OR, NOT. These operators MUST be in capital letters.
Example: (contact AND us) OR (about AND us)

All of these techniques can be combined: +alway* -ne??r*
