Hi Paolo, I wrote the patch to speed-up Boyer-Moore algorithm in KWSet at bug#17013. As next step, I want to be able to use it for case-insensitive matching, too. Further more, I wrote the patch which when case_fold flag is set Boyer-Moore algorithm can be used for CSET at patch#17034.
However, this function is prevented from using the kwset for case-insensitive matching because it turns off case_fold flag. Norihiro
