Criteri e formula Nhibernate

Question

Ho una configurazione in cui ho un tavolo con due campi, il primo nome e il lastname. Per fare una ricerca nel nome, ho fatto una formula che contiene FirstName + " " + Lastname.

Ma se provo a fare la seguente affermazione:

Restrictions.InsensitiveLike("empl.FullNameFormula", "% " + restriction.PersonName + " %")

Ricevo l'errore:

"Il timeout è scaduto. Il periodo di timeout trascorso prima del completamento dell'operazione o il server non risponde."

Ma se provo a fare un uguale anziché come un simile funziona:

 Restrictions.Eq("empl.FullNameFormula", "% " + restriction.PersonName + " %")

C'è un errore con la formula e che cerca di fare un insensibile?

Sto usando la versione NHIBERNATE 2.1.2.4000.

Aggiornare:La mia stacktrace sembra così:
