ixVectorNextRecord
Name
ixVectorNextRecord
Synopsis
ixVectorNextRecord( OnixQueryVectorT Vector, RecordNumT *RecordNum, WordNumT *WordNum, RecordNumT *Count, FloatT *Weight, StatusCodeT *Status)
Arguments
Vector: A Query Vector created by ixProcessQuery or ixCreateResultVector.
RecordNum: A pointer to a integer of type RecordNumT. The next record number will be placed here.
WordNum: A pointer to an integer of type RecordNumT. The first word number for the next record will be placed here if you have a WordLevel index.
Count: A pointer to an integer of type RecordNumT. The number of times this word occurs will be placed here assuming the index is of type IDF.
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.
Returns
Nothing.
If an error occurred, Status will be set to the error number. At the end of the Query Vector, Status will be set to EndOfHitList.
Description
ixVectorNextRecord is almost identical to ixVectorNextHit except that it advances to the next record stored in the query vector and not the next hit. This is useful for WordLevel indexes where you may not want to advance one by one through all the matching words within a record. For Record or IDF mode indexes, ixVectorNextRecord will function identically to ixVectorNextHit. When advancing through the query vector and the end is reached, Status will be set to EndOfHitList.
