Searches on three letter words is banned on this forum. Unfortunately many useful abbreviations are three letters so banning all three letter searches severally limits the usefulness of the search facility. As a result to find similar posts, forum users are forced to hope an abbreviation plural has been used or manually page through the forum looking for potentially relevant posts. I appreciate the restriction is there to decease forum server load when searches on common words are attempted. Excluding words which are actually used too frequently (via black list or word count) would be preferred. Removing this restriction may result in a decrease in posts for similar suggestions and similar support.
