Strange Stuff at Google

Every once in a while I go google Starhawk to see where I am. I pretty much have not moved for about a year being the second to fourth starhawk listed.
All of a sudden about two weeks ago I dropped off the front page entirely and the next ten also for that matter.
I sent google a note and they sent me back a reply that I should try googling starhawk.net and see if I was still listed. I did come up but then I tried some other things.
I put in Starhawk+roses , almost nothing then,
starhawk+high hopes (a recent post) again I didn't show on the first ten or so pages ,very odd.
For comparison I went to Yahoo and did the same searches where I came in the top three results.
Then to Alta Vitsa where I put in the same searches, once again I was in the first page on both search engines but almost not on google at all. On google in fact my old blogspot site came in long before anything on starhawk.net.
I sent these results to google and asked them to try it. Once again I pretty much got a run around however today when I googled starhawk I was once again where I used to be.

Very strange.
