ixVectorCurrentHit
Name
ixVectorCurrentHit
Synopsis
void ixVectorCurrentHit( OnixQueryVectorT Vector, RecordNumT *RecordNum, RecordNumT *WordNum, RecordNumT *CountNum, FloatT *Weight, StatusCodeT *Status)
Arguments
Vector: A vector which has been returned from a function such as ixProcessQuery.
RecordNum: A pointer to a value of type RecordNumT. This is where the record number of the current hit is returned.
WordNum: A pointer to a value of type WordNumT. This is where the word number of the current hit is returned.
Count: A pointer to a value of type RecordNumT. This is reserved for future use.
Weight: A pointer to a floating point value of type FloatT. This is the final weight of the record which was used when ranking. If you did not do a ranked search, the value put into Weight can simply be ignored.
Status: A pointer to a value of type StatusCodeT representing any error conditions. When you are at the end of the query vector, Status will be set to EndOfHitList.
Returns
Nothing.
If an error occurred, Status will be set to the error number.
Description
ixVectorCurrent hit returns the current hit in a query vector. When a query vector is returned, the current hit is the very first hit (or entry) in the vector. ixVectorCurrentHit allows you to see what it is. You can then use ixVectorNextHit to see what the rest of the entries are.
