Once you've created the query to search one field, you can modify the query
to search more than one field, like this:
"SELECT * FROM tblnames WHERE (firstname = '::firstname::') OR (middlename
= '::firstname::') OR (lastname = '::firstname::')"
If you are editing the page in HTML or Code view, make this change in the
gray colored code and save your change before you switch back to Normal or
Design view.
OR means any of the conditions can be true
AND means they all have to be true
