EVI Symbol Table Probe

The EVI Symbol Table Probe icon indicates that the selection criteria whose predicates matched the leading key columns of the encoded vector index will be used to probe directly into the symbol table portion of the index (the symbol table contains all of the distinct values in the index). Only those distinct values that match the specified key selection will be selected out of the symbol table.
