Using a Find statement with user input, not selecting the right table entries

I have a search form that takes user input, and displays the results
in a search_results.rhtml view. In my controller for the search form,
I have the following declarations and am using the call to "find":

beds = params[:beds]
baths = params[:baths]
sqft = params[:sqft]
neighborhood_id3 = params[:neighborhood_id3]
neighborhood_id4 = params[:neighborhood_id4]
neighborhood_id6 = params[:neighborhood_id6]

@properties = Property.find(:all, :conditions => ["AREA like ? OR AREA
like ? OR AREA like ? AND NO_BEDROOMS >= ? AND NO_FULL_BATHS >= ? AND
SQUARE_FEET >= ?", neighborhood_id3, neighborhood_id4,
neighborhood_id6, beds, baths, sqft])

Then I display all the properties returned in the search_results.rhtml
view.

The neighborhood part is working. These are checkboxes on the search
form, and if you check neighborhood_id3, you get only that
neighborhood returned in the result. However, the beds, baths, and
sqft, are not working. The entries that are returned are not within
what the user selected, ie: only show properties with beds > 2 does
not work.

Can anyone see what the problem is in my find statement? In my sql
database, I changed the types to varchars, thinking that they had to
be strings to do the comparison. Not sure if that is true, but it
didn't help me in any case.

Maybe someone could suggest a more elegant implementation as well ...
this does seem a little brute force?

Thanks in advance!

You need parenthesis around all of your or'd AREA conditions to get
them to work properly with your and'd conditions:

(AREA like ? OR AREA like ? OR AREA like ?) AND NO_BEDROOMS >= ? AND
NO_FULL_BATHS >= ? AND SQUARE_FEET >= ?

The parenthesis were key, and I also needed to change the first AND to
an OR. That gives me the results I was looking for. Thanks!
