Examples of QueryWrapperFilter

org.apache.lucene.search.QueryWrapperFilter
Constrains search results to only match those which also match a provided query.
This could be used, for example, with a {@link TermRangeQuery} on a suitablyformatted 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 TermRangeQuery would only need to be reconstructed once per day.
