I am preaching this for months now. It's getting so bad that I again started thinking about writing my own search (crawling my top 20 sites and a search depth of 2 for linked sites + wikipedia + IMDb + Wiktionary).
Google "correcting" or flatout ignoring search parameter is infuriating to say the least and I'm finding myself more and more relying on my bookmarks and synched history for visiting sites I knew I visited.
