Some of the warnings are impossible to include or exclude in a search, such a d/s, n/c, and others with a slash, and it makes it difficult to search for specific types of stories or avoid some.
I can understand that you cannot change the way the search engine works, however is it possible to change such warnings in a way that they will not interfere with searching? Unless the My SQL Bolean search mode does this, in which case... please post a link so those of us uninitated knows what it means...
Also, wouldn't it be prudent to post a directory to the warnings outside of the author panel, so guests will have a fair chance of knowing what they get themselves into?
