SearchArgument (Hive 1.2.2 API)

```
public interface SearchArgument
```
Primary interface for SearchArgument, which are the subset of predicates that can be pushed down to the RecordReader. Each SearchArgument consists of a series of SearchClauses that must each be true for the row to be accepted by the filter. This requires that the filter be normalized into conjunctive normal form (CNF).
