I have also found that search results are getting frustratingly worse. Often even when I put in explicit search terms and quotes, and filter out words that I don't want, Google will return results that don't adhere to what I am looking for or just return no results at all. I remember when I would search for something and find much more relevant information. Now the first 5 or 6 search results are ad-sponsored and aren't relevant, but I have to go to the 3rd or 4th page to find something that matches. I also often have to search for things that were posted in the last year or less because the older postings are increasingly irrelevant.
