5.2.3. Understanding Results

Luke can be used to determine why a result appears (or does not appear) in the expected query result. The Query Module also offers the Lucene Explanation object for a given result (in a given query). This is an advanced class. Access the Explanation object as follows:
cacheQuery.explain(int) method

This method requires a document ID as a parameter and returns the Explanation object.

Note

In terms of resources, building an explanation object is as expensive as running the Lucene query. Do not build an explanation object unless it is necessary for the implementation.
