It looks like the filter is doing something (since without it, I get about a 
thousand times the results - 22700 vs 22).

However its not clear its working well:

ogrinfo -ro -al "CSW:http://geodati.gov.it/RNDT/csw" -where "subject LIKE 
'commerciale'"
INFO: Open of `CSW:http://geodati.gov.it/RNDT/csw'

  abstract (String) = Il dato contiene l'aggiornamento degli edifici e altri 
manufatti derivati dalle diverse edizioni della CTRN. I dati sono stati 
prodotti a partire da una selezione di elementi derivati dalla CTRN (edifici 
residenziali, edifici produttivi commerciali, cimiteri) e successivamente 
aggiornati attraverso fotointerpretazione di ortofoto. Il dataset deriva dallo 
shape file elaborato dal CSI per il Progetto Rapporto Stato Territorio ed è 
stato modificato dal Settore Territorio e Paesaggio selezionando soltanto 
l'edificato residenziale e produttivo-commerciale ed apportando alcune modifiche

So its perhaps matching other_subjects or abstract field instead?
