A refined search is supported by using two search forms, where the second form is integrated into the results template which complements the initial search form. In a refined search, you can enter a query, see results, and then indefinitely enter subsequent queries which are run only against each subsequent set of results. The search terms for the second query are appended to the first automatically.
Refined searches can produce more accurate and useful results.
The Initial Search Form You can use any search form to begin a refined search. The only change that may be required to the initial search form is to edit the results template choice if you do not want to simply edit one of your existing templates. In the following examples, possible changes are described for the Simple and Power search form templates. The sections below describe how to modify sample search forms to support refined searches. In the Simple search form, the results template is already set to the Simple Results Template, smplrslp.hts .
