#search 2 hashtags

I have been adding quite a few more search engines to #serci today, including #Fireball, #SearX/#SearXng, #eTools, #TigerCH, #WolframAlpha and #DBLP today.  All new additions are already live at https://search.jayvii.de.

With 64 search engines in the default configuration, I feel like the webfrontend has to present all the options in a better way. But I am really out of ideas on what that could look like... Suggestions are very welcome! #webdev #php #foss #search

Per my last post (https://social.jayvii.de/objects/tHRArkhwOLg) about bang-search: Do you know of any super-specialised #search engines that are worthwhile including in my little fun project traserĉi?
