Arguments
idx The index handle.
pWords Pointer to the words to add to the index.

Description
The avs_addword procedure adds words to the index. A word is defined 
as a contiguous string of alphanumerics, bounded by non-alphanumerics 
(like spaces and special characters), as defined in the ISO Latin-1 
standard.
It should be called by a filter procedure, which prepares a block of 
text for indexing. The avs_addword procedure returns the number of words 
added to the index. Usually, the next call to avs_addword will be given a
starting location which is *pNumWords (the number of words added) higher 
than the last call.

Return Values
AVS_OK or an error code.
