Is Tools the correct component for this issue? I would have thought it
should be Test?

> i.e. there are two indexes t1_c1c2 and t1_c1 on table t1. Execute "select * from t1 --DeRbY-pRoPeRtIeS
index = t1_c1c2"  on t1. Then,RuntimeStatisticsParser.usedSpecificIndexForIndexScan("T1","T1_C1C2")
will return true, while RuntimeStatisticsParser.usedSpecificIndexForIndexScan("T1","T1_C1")
will return true too. It's not correct.
