[gdal-dev] A CSW query that seems to me works badly

hum, well you actually hit a bug in the OGR OGC Filter code I've just 
fixed per https://github.com/OSGeo/gdal/pull/6713

With the fix the query sent is now:

HTTP: These POSTFIELDS were sent:<?xml version="1.0" 
encoding="UTF-8"?><csw:GetRecords resultType="results" service="CSW" 
version="2.0.2" startPosition="1" maxRecords="500"

ricettive"</ogc:Literal></ogc:PropertyIsLike></ogc:Filter></csw:Constraint></csw:Query></csw:GetRecords>

That returns zero feature. That said, I'm not sure that is what you want 
to do, since the server should really look for a dc:subject whose value 
is "Impianti e strutture ricettive", with the double quotes.

Probably -where "abstract = 'Impianti e strutture ricettive'"  is more 
what you want. But that returns also 0 features
