/*
Function: iSrchFilterGetSearchBitmapFromFilter()
Purpose: This function collects and searches filters and returns
a bit map if there are any filters.
The filter can either be a list name (mapping to a file),
or a list of terms. If it is a list of terms, then each term has to be
comma separated and must not contain any spaces.
A search bitmap will not be allocated if no terms were found
and an existing bitmap was not passed
Parameters: pssSrchSearch search structure
psiSrchIndex index structure
uiLanguageID language ID
pspfSrchParserFilter search parser string filter
uiStartDocumentID start document ID restriction (0 for no restriction)
uiEndDocumentID end document ID restriction (0 for no restriction)
ppsbSrchBitmap return pointer for the search bitmap structure
Globals: none
Returns: SRCH error code
