[Demexp-dev] List by category

[Lyu Abe]

Hi again,

actually retrieving question by category (when you click on one of the 
question category) is working, but only works with the current list of 
questions that are loaded on the question list page. In other words, you 
have 312 questions, only 100 are displayed at a time, so the category 
search will only work on these 100 questions. I'll implement the correct 
behaviour by this evening.
