void prNumHits( OnixQueryVectorT Vector,
UFloatT *VecWeight, ULongT *NumHits, ULongT *NumRecords, ULongT
*NumWords, StatusCodeT *Status)
The list of hits you wish statistics on.
A pointer to a float with the overall weight of the vector. (Currently
A pointer to a long integer with the total number of hits in
pointer to a long integer with the total number of unique records
in the vector.
A pointer to a long integer with the total number of words in
the vector. (For compatibility with Onix - is the same as NumHits
for the Profiling Engine)
A pointer to a value of type StatusCodeT representing any error
If an error occured, Status will be set
to the error number.
prNumHits() gives you statistics on the
vector returned by prProcessQuery(). It will tell you both the
total number of hits and the total number of unique records in
Typically you will call prNumHits() prior
to iterating over the hits in the vector using prVectorNextHit().
