Anyone <!here|@here> has ever tried to search website categories with a filter. I am trying to filter to on

parentcateogry

and

itemid

fields but its throwing error:

An nlobjSearchFilter contains invalid search criteria: parentcategory

. Here is code:

nlapiSearchRecord('sitecategory', null, [
            new nlobjSearchFilter('parentcategory', null, 'is', ''),//@NONE@ doesn't work either
            new nlobjSearchFilter('itemid', null, 'endswith', 'Catalog')            
        ])
