I have a FAQ with some mains categories, each of them with sub categories like
If i make a search from the index page, the engine will look everywhere and i have the good result
If i select in the vertical menu the II category, the search engine return ... 0 result
If i select in the vertical menu the II category then the e subcategory, the search engine return ... 1 result
Seems the seach engine don't look on sub categories if i'm not at the index page .... is it normal ?
