Why does this board's search fail so often?

[Bob R.]

I could probably find my answer if the search wouldn't keep giving me back this response:
The following words in your search query were ignored because they are too common words:
words or strings like:
ignore lines
ignore lines compare
... what am I missing?

Please try now.

I also had some problems e.g. "command line" etc does not work in search.

The search should be working now.

Thanks! I missed the response until just now. Does this forum automatically subscribe you when your the author? If not, could that be an option?

I don't see such feature in phpbb that these forums are based on.
