I'm wondering if anyone has suggestions to make the article module search feature more robust.

I just added about 20 years worth of articles to it (so i ideally don't want to use something different), but I'm looking to:

search multiple keywords at a time.

For example: authors last name is sanders and i want to see everything she wrote on cats so I want to search

"sanders, cats"

and nothing comes up, but if i just search one or the other it works.

Any ideas?
