[arch-general] Akonadi file content search

Hi girls and boys This may seem like a daft question, and I did research this at length on Google, but is there any frontend that one can use to search file file contents? I understand that Akonadi contains meta data and that nepomuk feeds it and that everything ends up in (my case) a MySQL database (tables). Apart from the krunner interface, is there a front end that allows you to specify more than one criteria on a search? Or possibly is there a backend that can do advanced searching? PS: Yes one can query MySQL, and yes, there is akonadiconsole but that does not seem to have an item search for files. Thanks Andy
