@Dr-Flay , this was also my idea at the beginning of using a meta-search, for example SearX, but I realized that, although they use engines like Google, Bing, etc., these did not work fully as in the original. Especially when searching for images I constantly had problems.
For this reason, I currently have the most efficient search results using Andisearch as the main engine and different engines, such as Dogpile, Qwant, PaulGo, etc. and specific engines, such as Wolfram Alpha, Wikipedia, site search....., apart from an extension to search for images from the context menu, where I choose Yandex, as it is by far the best and most complete for this purpose.
It is quite comfortable in the search bar to put the concept and carry out the search after changing from one engine to another, or to make queries in the address bar with Andisearch, where I have a direct answer.
