advanced search forms with 3 input text

[hope10]

N.B. : all my work is on wordpress.

I was working for an advanced form with 3 input text in purpose to show a list of hotels.

The problem is i tried an infinity tricks and functions but without any results, the only result i got is when i search with tag, but i have also search by adress and rating.

another problem is i used in the first time a custom taxonomy in the first way then i used metabox but nothing i can't find how to show results.

this is the form

i hadn't a really good idea what i need to do so i tried meta query if (!empty($adr)) { $meta_query[] = array( 'taxonomy' => 'adresse', 'value' => $adr , 'compare' => 'LIKE' ); } in funtion then i call this function in search result but nothing shown
