let's say you want to locate across the code and description fields when the browse is sorted by description.
go to the description field.
go to the "sort" tab
down the bottom; "Locate on fields" (comma separated list)
'fil:description, fil:code'
rinse and repeat for other columns (maybe the code column in this example?)
only works for strings - and only works for "exclusion" locators, like contains, begins with and search.
