If your data is in an SQL-Database you could use input forms which result in
SQL-Statements  "select from table where column like <dtml-var input_field>".

Or you can use ZCatalog. I didn't use ZCatalog for an sql-database yet. But
it works fine for python products. You can keep your index always uptodate if
you call seld.index_object every time you change properties which are cataloged.
Your class needs to inherit from CatalogPathAware.CatalogAware.
