When we use Web research (Web clipping, note taking) tools it means that we have found a Website or get info about it in other form.
As concering search I typically use a few different types seach engines
Some search engines enable to get an additional information about related terms, other generates list of topics etc.
Kartoo generates some visualisation of results etc.
Typically I start to collect realted terms to my first query and compare different search results.
There are more search engines, eg. DerepWeb search. I shall present some info about them on the following blog.
