 The search engine has a bit of a problem showing spicy content mixed in with the results.  It would be desirable to have a way to filter this out.  It's likely something like a URL blacklist (e.g. [UT1](https://dsi.ut-capitole.fr/blacklists/index_en.php) )
 combined with naive bayesian filter would go a long way, or something more sophisticated...?

 I've talked to the stract dev and he does not think it's a good idea to mimic their optics language, which is quite ad-hoc, but instead to work together to find some new common description language for this. 
 
+## Show favicons next to search results
+
+This is expected from search engines.  Basic proof of concept sketch of fetching this data has been done, but the feature is some way from being reality. 
+
+## Specialized crawler for github
+
+One of the search engine's biggest limitations right now is that it does not index github at all.   A specialized crawler that fetches at least the readme.md would go a long way toward providing search capabilities in this domain.
