[GeoNetwork-users] PropertyIsNotEqual not working in GN 3.2.0

Hi,

I have problems with PropertyIsNotEqual filter in GN 3.2.0. This request gives me 0 results:

<?xml version="1.0" encoding="UTF-8"?>

<csw:GetRecords xmlns:csw="http://www.opengis.net/cat/csw/2.0.2&quot; xmlns:ogc="http://www.opengis.net/ogc&quot; xmlns:gmd="http://www.isotc211.org/2005/gmd&quot; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance&quot; xmlns:apiso="http://www.opengis.net/cat/csw/apiso/1.0&quot; service="CSW" version="2.0.2" maxRecords="20" startPosition="1" resultType="results" outputSchema="http://www.isotc211.org/2005/gmd&quot; outputFormat="application/xml">
  <csw:Query typeNames="gmd:MD_Metadata">
    <csw:ElementSetName>full</csw:ElementSetName>
    <csw:Constraint version="1.1.0">
      <ogc:Filter xmlns:ogc="http://www.opengis.net/ogc&quot;&gt;
        <ogc:PropertyIsNotEqualTo>
          <ogc:PropertyName>Subject</ogc:PropertyName>
          <ogc:Literal>Ei-Inspire</ogc:Literal>
        </ogc:PropertyIsNotEqualTo>
      </ogc:Filter>
    </csw:Constraint>
  </csw:Query>
</csw:GetRecords>

I get plenty of results when I change PropertyIsNotEqualTo to PropertyIsEqualTo. The most of our metadata don't have the "Ei-Inspire" keyword and therefore the NotEqualTo query should give me a lot of results too.

I tried also to configure a virtual CSW endpoint with this kind of not-filter but it has problems too. Actually it works in the opposite way that it should work. It gives as a result the metadata that include the "Ei-Inspire" keyword when it should return those that don't have that word.

I already rebuilt and optimized the Lucene index but it didn't help.

Is this a valid CSW/Lucene issue in GN 3.2.0 or am I doing something wrong?
