Autoblog filters

Sorry, I can't find an answer from this so far in the manual documentation or on the support forums. When I use the filters in Autoblog, will it filter by phrases, or does it single out each individual word?

For example, I want to filter in posts that use any of the following phrases:

-Start a business, work from home, work at home

Will this work as I have it listed where each phrase is separated by commas, do I need to put quotes around the phrases, or is it going to filter by each word no matter what (so, if a post has the word "a" or "from" in it, it will be included, even though it doesn't have the whole phrase)?

Thanks,
Geoff
