Did Google change something? Quotation marks in query

[keyon]

I normally place quotation marks around my keyword searches - but now this doesn't seem to work anymore. For example, Google is reporting 150k results for an exact keword phrase that just last week showed 20k.

Andy ideas?

Google is constantly changing things. I think they make over 200 minor algorithm changes through a single year. It makes sense for them to offer more results for users, even if they use quotations.
