Custom Search for Custom Post Types

hi,

I am hoping someone can point me in the right direction… I created custom post type for Property Listings, and I am trying to create a search form to query the metadata within the custom post type… for example… a user would be able to select number of bedrooms/bathrooms from a dropdown, search by city(which is another custom field) … etc

I would like to do this without the use of any plugins…
Really grateful for any help.
