Included here are templates for search boxes. Just copy and paste the code, modify it according to your needs and you're done. It's that simple.
A stripped-down template for the minimalist approach
This first template is very simple. It gives the user no options to define his own search--you as the webmaster define all the parameters by default. It represents a bare-bones approach.
This template illustrates how to give options to the user. In this example involving the Agriculture Institute, the user is presented the option to search the entire ag collection or to hone the search to the indicated specific sub-domains. Radio buttons and qp variables are used to implement the choice.
