Is it possible in the HTML form to input one expression that will be compared against all fields except say a category field, so that the result output will be all incidents of the expression, but only for the specified category. Inputing 'keyword' seems to compare all fields and using any specified filed only allows comparison against the one field. I want to setup a simple form that will allow searches against one expression for all fields except the catgory field to allow users a selection of categories plus a * selection for all categories. How can I do this?

Thanks in advance
