well i have some basic knowledge of this. so i will tell you what i know.
i take it that you have filled in your fields and created your table.
minimize your table and select querys. then out of the pop up select create query in design view.
it will the pop up with "show table", select add. you will then have your query table. you add your fields with the little drop down menu.
you can then create your query. you leave the box ticked in each feild you would like the query to applie to.

so you can do normal query's right? anyway you need to create 2 or more tables to search through the tables, once you have done that setting up and advanced query's are easy. i will write a quick help file later becasue i have to be going .. lol , soz
