We have an index of 25 fields. Currently number of records in index is about 120,000. We are using
parser: edismax qf: contains 8 fields fq: 1 field mm = 1 qs = 6 pf: containing g 3 fields bf: containing 1 field We have noticed that sometimes results change between two searches even if everything is constant. What we have identified is if we reindex data and optimize it remedies the situation. Is that expected behavior? Or should we also look into other factors? Thanks
