- com.yahoo.search.predicate.annotator.PredicateTreeAnalyzer

```
public class PredicateTreeAnalyzer
extends java.lang.Object
```
This class analyzes a predicate tree to determine two characteristics: 1) The sub-tree size for each conjunction/disjunction node. 2) The min-feature value: a lower bound of the number of term required to satisfy a predicate. This lower bound is an estimate which is guaranteed to be less than or equal to the real lower bound.
