can't search for iso, pdf

[robvonk]

I tried searching for 'chart' AND 'pdf' AND 'iso' but it complains about this:

The following words are either very common, too long, or too short and were not included in your search: iso, pdf

So i will get all posts with 'chart' in it. Any way to include only posts with all three words in it?

You need to search for more than just 3 letters. ISO and PDF are so common it would return about 22,000 threads and is too server intensive. Try elaborating you're search. I don't allow anything shorter then 4 letters on my VBulletin forum.

I can understand that but the combination of the three wouldn't give that massive results so it can be usefull.
