Advanced Search (length, width)

Hi,

I use the Directory Theme and have the Taxonomies plugin. I will explain what I want to do by giving you an example:

I have these four companies on my site: NP SA, PL LTD, BK CO, LM SA. Each one of these four companies has one or more warehouses

1) NP SA: warehouse (100 length x 50 width)

2) PL LTD: warehouse (200 length x 60 width)

3) BK CO: warehouse (300 length x 70 width)

4) LM SA: warehouse (400 length x 80 width)

I want to make an advanced search in which the user will choose which company is best for his needs by searching by length or width or both.

Example: the user will write 123 in the search field Length and 45 in the search field Width. Then he will click on search to get the results closer to his criteria or the exact match.

Since I use the Directory Theme, where shall I write down the information: warehouse 100 x 50 ? Must I write it on the Description tab, Details tab or it doesn’t matter?

How will I make this Advanced Search option?

Thank you in advance.
Iason
