content: I used to swear by it but recently I noticed the searches were not as good as they once were, and when someone else mentioned it out too I tried out a few others and I'm glad I did.  Now I have a bookmark folder just for search engines so im not just relying on a single one, but i think Searx.me is the best of the bunch for me, good results and they're privacy oriented too so no "profile generated results" like google. But if your on windows I dont think it matters what you do. If your concerned about privacy I would recommend a privacy oriented browser like Waterfox (A good old days version of Firefox).
