I am trying running the self-hostable meta-search engine software, Searx, on Localhost. Because I use Manjaro Linux, I installed the Searx package from the AUR (the two -git packages did not work out of the box for me). So far it works flawlessly and on Firefox it is able to fetch results from Google. I will learn a bit more about it and possibly write a review in the future.
A few resources for those who are interested in learning more:
I am also planning to work with Yacy to build my own local index.
