RSS Tool Keyword Filtering Feature Question

[vader2]

The VB RSS tool allows to only display feed items that have certain keywords in title or text of the news item. But.. my concern is that it does not seem to be flexible enough:

I need to filter the RSS feed with a logical construct such as:

DISPLAY IF:
TITLE HAS "JUNGLE" IN IT OR
(TEXT HAS "MONKEY" AND "JUNGLE") OR (TEXT HAS "LION" AND "JUNGLE")

My impression is that the standard keyword filtering avalable with the RSS tool cannot be that flexible - right?

And if it can't - how can I achieve the kind of filtering that I need? I'm willing to pay for it if needed.
