Dear TC.K;
Thanks very much for your great plugin.
in fact this is exactly what i want;
I could use it to add a meta field check-box to query data by user.
but even "generation value" works completely fine in back-end, however when select one check-box, no result is shown in front-end. and show this:
Nothing Found
Sorry, but nothing matched your search terms. Please try again with some different keyword
i used both ajax and default search template. also check with radio button and combo box. no one answered. i am using wp 4.4.2 and also disabled unused plugin. i don't know what goes wrong. everything works fine except the result. (the built-in wp search widget also works fine). I would appreciate if help me to use and get result.
thanks very much.
Ali
