SORRY- Google are unusable these days, serving myriad bad results AND refusing to give results if you make intelligent filtered searches, and don't use javascript (using a javascript only no-robot captcha). Google now as a matter of policy downrank private http websites and uprank spammy no-content sites that tick the right boxes (= most recent technology), or that pay them (or they own). Please do try the following search engines.
When researching on the internet, try not to limit yourself to one search engine. There are very few useable search engines left. I will not use any that insist on javascript. Search engines regularly modify their algorithms to reduce hijacked results (sometimes works, sometimes makes things worse!) so your favourite today could serve you junk tomorrow (and be back to best next month).
The various search tools have differing sets of web pages and differing algorithms. For difficult subjects it is usually best to use two or three search engines at least.
I have found it advantageous to try some of the other search engines below.
Duckduckgo seems to serve me a lot of irrelevant pages and omits the obvious ones.
