Package org.graylog.plugins.views.search.validation

Class FixedBooleanQuery

java.lang.Object
org.apache.lucene.search.Query
org.graylog.plugins.views.search.validation.FixedBooleanQuery
All Implemented Interfaces:
Iterable<org.apache.lucene.search.BooleanClause>
public class FixedBooleanQuery extends org.apache.lucene.search.Query implements Iterable<org.apache.lucene.search.BooleanClause>
The default BooleanQuery from lucene uses Multiset implementations in the visit method. These lose the reference to the actual query instance and aggregate queries if they are the same. This breaks our terms detection in validation. So we have to provide this alternative class that iterates bool clauses with correct references
