Important: don't repeat the item selector in title/link/desc/date selectors. Think of the item as the div container for, say, article, and item details as child/nested elements inside each article.
JSON pages: internally converted to HTML (nested div elements); read more here.
Pro tip: filters are inclusive - they include items that match the pattern. To exclude, use a negative lookahead, e.g. /^(?!.*(perl)).*$/ matches everything except strings containing "perl".
