There are hundreds of SEO-optimized websites that basically post obvious shallow information and still achieve to trick search engine algorithms with great effort. I don't want those shallow information articles. There's wikipedia always for surface introduction of the topic.
Examples of such sites include GeeksForGeeks, Many medium blogs, DZone, ZDNet etc..
Are there any search tricks / filters / alternative search engines or proxying search engines that allow to avoid bullshit tech content?
1. Use more specifically targeting words. I.e. I needed a specific valve for a new gas line I put in a few months ago. The kind of thing that’s not sold at Home Depot, but at wholesale outfits specifically tailored for plumbers. Instead of search for “3/4 gas valve” I searched for “3/4 gas cock” as “cock” is an industry word for “valve” and the results of which would get me more precisely to the sources I was looking for.
The same can be used for technical stuff. An example, instead of searching for “how do I add a firewall rule to a router” I’ll search for “cisco allow udp 53 rule”.
2. Often I find that the same couple sites are the places that have the specific information I’ve looked for in the past. I do this for product reviews as an example: “cove security reddit”. For a more technical example, during the gas line, I searched: “3/4 gas 10” WC Reddit”. This got me into a few conversation threads where a master plumber was explaining the max BTU usage I could have on a similar line to mine, he then explained the math behind it with some very valuable knowledge from his experience on permitting and gas company nuances. Exactly what I was looking for.
These are two basic examples that show methods that work super well for me in finding what I need and skipping the bullshit out there. These combined with learning Googles operator syntax is the ticket.
You could go as far as messing with DNS or some blocking methods, but that seems likes a ton of work for little return. Just learn how to search a little better. :)

2) Using Host Files, i think that you can block domains of the sites that you are not interested.
3) Search Individual Sites .
Instead of Searching the whole web , there are some sites which contains good resource of certain field. If you are searching from that certain field, first search that site.
I save all my search terms as I proceed (and record all word-stemming, plurals..), and indent hits, and then search for cites and indent again where hits, then when a sub-search dries up I start again with a new string and so on. I find it saves a lot of time, reduces saving junk and I can always go back. And I get a valid cite chain.
I search in epic-browser as it cuts down the clutter. Mostly on scholar (I turn off citations and patents and usually start with all years as some things are mis-dated, this also and issue with ResearchGare where their pub date May be decades after the paper date), sometimes the open web (altho' mainly on specific domains; .edu .ac ..). Some countries I exclude.
