remove the four-character search term limit

[halogen]

you can't do a search on this forum if the search expression is shorter than 4 characters, or only consists of words that are shorter than that. this is quite a limitation because IT is full of three-letter abbreviations. for example, I wanted to look into the topic of LTE, but of course I can't search for either "LTE", "4G" or "LTE 4G". this is just the most recent example from the many so far.

can the administrators please lower or remove this limit? it would make the forum much more useful!
