If I try to do an Internet Search with the exclusion "-nz" (not in quotes), it doesn't work. I still get tons of posts that have "nz" in their title.

In fact, testing this further, it seems that exclusions don't work at all unless they have at least five characters. This negates a lot of functionality of that feature.

It can be worked around if you know how to do it via regex, but it seems to force an unnecessarily complex workaround when a simpler solution already exists.

The limit is 3 characters. We do not index one and two character words.

Hmm. That must be tied to the version - for 6.72 B4776, I couldn't get it to work with anything under 5 characters.

No problem. RegEx to the rescue!

The limit is at the server, not the client. I can look into it but negation should still be 3 characters or more.

RegEx is a good solution, it can be applied to your search results to whittle things down more.
