Advanced GREP searches
only from this page. Please read the warnings carefully. 100
hits is the maximum.
If your results are
all in red, you messed up. Redo your search.

•Don't experiment.
•Please be sparing
of Kleene's star (*). Please don't begin or end your regexp with
it unless absolutely necessary.
•
Try to begin and end your regexp with \b. Grep is greedy, so
you might otherwise overrun word boundaries.
\b(&t;eod)..?\b
finds lowercase theod, theodne, theode, etc. (&T; for uppercase.)
\bg(i)?eld\w+\b
finds geildan, geldan, geldenne, etc. (a . instead of \w
will ruin the search). Note that the parentheses are not necessary.
