The indexing and querying is implemented via Hibernate Search which sits on top of Lucene. Lucene has no concept of null. Null is emulated by Hibernate Search by using a special (non-null) string marker value (the dreaded null token), but this only works for strings; for other types this fails silently. This limitation cannot be solved with Lucene 3.6 and 4. A better approach might be possible with 5. |
