Words shorter than 3 characters cannot be searched for, nor can words which are too common, nor words which appear on the stop list.
I think you mean 3 characters or less. Which is somewhat problematic for a user group that discusses things like: MFM, HFS, MFS, DOS, ROM, etc. According to the
phpBB3 docs, the number of characters is controlled by the administrators. Not sure if there is a reason to limit it like this. Are they protecting us against some kind of spam attack? I'm guessing it likewise is there to reduce bandwidth and resources going towards searches for word's like "a", "an" and "the".
Also, it further specifies that the admin. can set "common words". Obviously "Plus" is going to appear quite a lot. By that token, so is Performa, Quadra, Power, etc. Again, I assume the only reason to use this filter is to reduce drain on the server.
Nothing is mentioned of the "stop list" in this documentation. But I would assume if there is a stop list, there is also a "pass list" which allows certain otherwise restricted words to pass?
Hopefully, in future updates there will be a way to deal with this. I'm certain topics have been covered before but I can't search them because it is not possible. No wonder things I remember don't show up in search results. Some kind of keyword feature for each thread would be helpful so that we can all search by known terms like "macse" and "maclc", along with a tutorial.
