Range search get data outside of range
I am using DBSight 3.3.2(b266)
I have a field that is saved in the form 20110701.
If I search using somefield:[20110701, 20110702]
I get back data from 20110701 to 20110703, maybe all the way to 20110704.
If I search on a range that is not in the data I can still get results for field data that is close.
ie somefield:[20110709, 20110710]
I get results that have data for 20110707 and 20110708.
Also, if I do a general keyword search and I know that there is only one result possible and I use the range search also for a range that is outside of the one possible result I still get the one result
ie in the url I have q=S4ABCDEF+somefield:[20110709, 20110710]
I still get S4ABCDEF as a result even though the somefield for S4ABCDEF is 20110707
What is going on?
Is there a way to stop fix this behaviour.
