Here are some good starting points for browsing.
Here's a title search. Try something like wiki or sandwich.
Use the following for a full text search. This takes a few seconds. The results will show all lines on a given page that contain a match.
In a FuzzyPage search the titles of all pages are examined to find those which are similarly spelled or similar sounding (english).
Separate words with a space. All words have to match.
To exclude words prepend a '-'.
Example: 'wiki text -php' looks for all pages containing the words 'wiki'
and 'text', but not containing the word 'php'.
