In addition, there are several ways to modify the default search behavior.

1. 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}
     
2. + 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
3. * 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: Pierz* [searching for A.J. Pierzynski but don't know how his name is spelled]
4. ? wildcard
   If a query word contains a ? any character will match that position.
   Example: ba?e [Will produce pages containing babe, bare, & base]
5. boolean search
   You can use the following boolean operators in your search: AND, OR, NOT. These operators MUST be in capital letters.
   Example: (catcher AND mask) OR (gear AND catcher)
