Comment 5 Van Halbert 2015-07-02 21:46:14 UTC 
The following are 3 columns that were queried but didn't work:

- timeValue is Null

- booleanvalue Is Not Null

- intKey Is Not Null



The following is the 1 query that did work:

- stringNum Is Not Null
Comment 6 Adrian Nistor 2015-08-18 12:47:41 UTC 
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.
