Use wildcards in any of the blanks. These will work in the main search page, as well:
Basic search ignores dash (-) and glotta ('). Wildcard searches are sensitive to these characters.
Most blanks search for entries that contain that term.
Example: hamyo in 'Examples' returns entries with hamyo anywhere in the example text.
'Entry' however, is exact by default.
Example: ham in 'Entry' returns ham, but not hami unless you include wildcards (for example: ham*)
