Rooms Availability Serach

Hello,

I'm using version 7.x of drupal with rooms module. I wonder how to make Availability search view for drupal Rooms or edit the one that exist when you install Rooms module ( Picture1).

What i want to have is date search which already exist but i want to remove unit and group size field ( becouse group size is limitted up to only 20), also i want to add some other filters exposed to visitor such as location, capacity (in case conference rooms ), etc. So, when visitor choose data, location and capacity and when visitor click button "search for availability" to show all available contents which corresponding to the given criteria.

I know how to add taxonomy filters such as location, capacity and so on, but i'm having trouble with data search availability. Please, can someone help me with this problem and give me the best solution.
So in other words, i want to connect Picture 1 and Picture 2 in one view.
(sorry for my bad English, i'm giving my best)
