Function Code

Use the function code parameter of the RangeSearch command to determine how the results of a search request is to be combined with all other search results within a single pass.

The results from a restrictive request are ANDed with all other search results within the same pass. The results from a nonrestrictive request are ORed with all other search results within the same pass except from search requests defined as restrictive. The sum total of all search results within a single pass is then ORed to the results from all other passes.
