Editing and running a revised search is like running a new search and incurs another suggested chargeback value. Instead, use content-specific filters to narrow your search result list. For example, use
Search within results
to add more terms and refine your results.
Search within results
and the other filters are included in the value of the initial search. It's best to run a fairly broad initial search (see tip above) and then use filters to target documents. Apply filters multiple times to refine your search until you find relevant documents without triggering any additional suggested chargeback values.
