How to filter Aggregator feeds by keyword in Drupal 5

Hi,

In Drupal 4.7 I used to filter syndicated items automatically by keywords, so that only news items which contain a keyword were shown, trough news_page module (See drupal.org/node/13047).

There is no update for news_page module for Drupal 5, so I am wondering, what could be alternatives for achieving similar result.

I tried to use Views module to filter the syndicated content, but it seems that I am not able to restrict such View to feed items only. Moreover, the filter in news_page module was more powerful, as I was able to use syntax 'adv*' in the keywords (so anything that starts with 'adv' was filtered in), whereas in Views I need to type in all different keywords separately. The later aspect is very important for me, as in Estonian language the ending of the same word may change up to some 28 times, dependent on the context and on plural/singular form of the word.

So what would be the best options to go? Do some other syndication module have such an functionality?

thank you in advance,
Milosh
