Description: 
As for now HiveORC profile doesn't use any storage layer optimizations for LIKE

Current optimization could be applied:
1) Parse first token of LIKE clause before first occurrence of "%" symbol.
2) Apply ORC filter: >= AND <=

Where NEXT_TOKEN = .substring(0, .length() - 2) +  
.substring(.length() -2, .length() - 1) + 1
