Problems on filters

Hello Ernest,

I have 2 questions / problems i would like to fix about filters :

First question :
By default all my filters are unchecked.
When i go do on the filters and i select one category (wi no search entered in the main search input) I would like to display on results only the post related to this category. Its not the case actually, you can repro the main search on https://ajaxsearchpro.com

Second question :
If i type a keyword in the main search input then i’m going to filters to check one category, on the result i will have the good the post with the category associated but also all the post with no category assigned. How i can fix that ?

Thanks a lot,
