Hi Team I need to run a query something like select count(*) from tableName where columnName = 'Text' I added this columnName to bloomFilter Now Im trying to see the efficiency of the query while looking into the columns of numEntriesScannedInFilter 10 numEntriesScannedPostFilter 5 Number of scanned Filter is showing greater number than postFilter. Is it okay to be like this or by indexing doesn't work properly How do I verify the efficiency of the bloom filter that it worked? Under which indexing where clause column should be added. if its wrong to add under bloom Filter Kindly help me out plz #CDRCA57FC #C011C9JHN7R

This is expected. If you had total docs N, then only 10 of those scanned after applying index, and then further reduced to 5 for applying predicate
If you use inv index, it will be 0.

Will it affect the efficiency in later stages??

What’s in later stages?
n
when the dataset size or number of entries increases

In general, no. But need to understand your workload (use case, query, data size) if you are looking for recommendations on index tuning.
