Agreed, cant even count the amount of times I have searched for $VERY_SPECIFIC_THING on Google, but got 10 pages of completely irrelevant references to something that has close to matching keywords and is way more popular.
It seems pointless to try complete proper sentences anymore. Even specific queries about X often shows me "TOP 10 X!!!" or similar adcrap.
Oh maybe the decline of findability of specific things is caused by the increase of total things on the web.
