Problem with the Forum-Search-Function

Now i've tried finding post about the "dfgallery" but i always get this:

"The following words in your search query were ignored because they are too common words: dfgallery.
You must specify at least one word to search for. Each word must consist of at least 3 characters and must not contain more than 14 characters excluding wildcards."

am I doing something wrong or there no possible way to find a post about the dfgallery except for going through every post in every subforum?

I have adjusted the search settings and rebuilt the search index. Please try again.
