Hi,
How to search for null values?
Like get me all salaries <5000 now i need results with salary not set i.e null
Setting null term in RangeQuery/ConstantScoreRangeQuery is not working as that is being replaced bu [* TO 5000] or [ TO 5000] both not giving results
what i tried is
Code:
new ConstantScoreRangeQuery("field", null,value,
               false, true);


Regards

Null values are actually not indexed in Hibernate Search or Lucene as a matter of fact. You could use a custom FieldBridge together with a null token of your choice to solve your problem. This is related to HSEARCH-115.
