Class QueryWrapperFilter
java.lang.Object
org.apache.lucene.search.Filter
org.apache.lucene.search.QueryWrapperFilter
- All Implemented Interfaces:
- java.io.Serializable
public class QueryWrapperFilter
- extends Filter
Constrains search results to only match those which also match a provided
query.
This could be used, for example, with a RangeQuery
on a suitably
formatted date field to implement date filtering. One could re-use a single
QueryFilter that matches, e.g., only documents modified within the last
week. The QueryFilter and RangeQuery would only need to be reconstructed
once per day.
