public static final class MultiTermQuery.TopTermsScoringBooleanQueryRewrite extends TopTermsRewrite<BooleanQuery.Builder>
BooleanClause.Occur.SHOULD
clause in a BooleanQuery, and keeps the
scores as computed by the query.
This rewrite method only uses the top scoring terms so it will not overflow
the boolean max clause count. It is the default rewrite method for
FuzzyQuery
.

Add a MultiTermQuery term to the top-level query builder.

build(BooleanQuery.Builder builder)
Finalize the creation of the query from the builder.

protected int |
getMaxSize()
return the maximum size of the priority queue (for boolean rewrites this is BooleanQuery#getMaxClauseCount).
