All of these techniques can be combined: +alway* -ne??r*
- + 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: +William -London
- * 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: Samuel Tong*
- ? wildcard
If a query word contains a ? any character will match that position.
By default the search
engine tries to locate pages which have exact matches for all of the
words entered in your search query. If that fails, it then tries to locate
pages which contain any words in your search query. If that happens a
short message is displayed at the top of the search results indicating this
has been done.
