fuzzi on "Filter search?"

Hi,

i saw in my logfile that my users are often searching for stuff like "blue pictures", "green images" and so on.

as "pictures" and "images" is not part of the filename nor part of the tags, the search results are zero.

Is it possible to define a list of words which are being removed before the search is executed - or better - replaced? This way i could also handle characters like "ä" which are not part of the filenames or tags because in that case i use "ae" instead.

Thanks for your help!
