void ixVectorPreviousHit( OnixQueryVectorT Vector, RecordNumT *RecordNum, RecordNumT *WordNum, RecordNumT *Count, FloatT *Weight, StatusCodeT *Status)
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.
If an error occurred, Status will be set to the error number.
ixVectorPreviousHit is used to find out what the prior hit is in the query vector. It returns both the record number and the word number of the current hit. If you are using a record level index, you will not need to pay attention to the word number.
