Guides/references on performing effective internet searches

Depending on which engine you use,  your search is often curated based on what they know about you as well as your prior searches.
I.e. If you search based on particular topics,
I think the algorithm will include common..

Can you provide an example.
Info what you were looking for, detail?
What did you enter as the search criteria?

You could use quotes to group items that should be looked as a set versus as individual terms

Try using the same search in the three/four search engines to see ehat they return.

You need to do the basic first before doing a search.

What is the basic?

Reading sufficient background information regarding the subject matter and/or the specific question you need to answer so that you have an understanding of what context / keywords which will be relevant for your search.

It is the fundamental principle of data... rubbish in, garbage out. You should know/understand the problem by reading enough information instead of only using the words from your questions as keywords.

The above is what have been taught in Information literacy course in my Master degree in Library and Information Management.
