What difficulties are you finding with it and are you switching from Google? The results are as custom as Google given they haven’t scraped your life history so wondering if that’s it? I’ve been using DDG without any issues. About once every 6 months I struggle to find something so try the Google bang but have never found better results. In fact, I was shocked last time how crap the Google results were, just full of AI generated crap and SEO based crap.
To be honest, DDG is also struggling with that now as it’s based on Bing. I have been trying a public searxg but not found it very good so far.
