Have you looked at the OpenSearch Description file for your instance? It might be generated with an IP by SearXNG not knowing the hostname. The URL is probably https://search.home/opensearch.xml
.
If you want to examine the search engines in your browser profile, they’re stored in a json file compressed with a mozilla specific variant of lz4. The file is search.json.mozlz4
and can be unpacked to json with lz4json.
Your fellow competitors did not necessarily perform the search when they were at the pub. It could be a the john when they got home. Your data profile is still tied to them right now.
