Collection< SpanQueryPtr > clauses
Definition SpanOrQuery.h:24
virtual String getField()
Returns the name of the field matched by this query.
virtual void extractTerms(SetTerm terms)
Adds all terms occurring in this query to the terms set. Only works if this query is in its rewritten...
virtual int32_t hashCode()
Return hash code for this object.
virtual LuceneObjectPtr clone(const LuceneObjectPtr &other=LuceneObjectPtr())
Returns a clone of this query.
SpanOrQuery(Collection< SpanQueryPtr > clauses)
Construct a SpanOrQuery merging the provided clauses.
virtual String toString(const String &field)
Prints a query to a string, with field assumed to be the default field and omitted.
virtual bool equals(const LuceneObjectPtr &other)
Return whether two objects are equal.
