regexp question

I have a text and I want to match several words like this "(controller|
data|IT)?" at least one of the words in the group should be mandatory,
but I dont want to match a word that is part of another word like this
"datamanager" it should only match the word "data" or any other word
in the group.

Any suggestions?

classes for non characters:
^ Start of Line or Data
$ End of Line or Data
\b Word-boundery, change from \w to \W

- "(\b(controller|data|IT)\b)?"

But some letters like German umlaute may be seen as Non-Word-Elements,
depending on your the encoding.

In this cases you may try search for your words between non letters.
- "((\s|^)(controller|data|IT)(\s|$))?"

what about data-base?

thanks for the reply

I know about boundaries and such, just couldnt get it to work, now I
see why, I had tesed \b(controller...)\b which didnt work as intended.
