+Implemented a basic but functionnal Github-like search on federated tracks list (#344)
+
+
+Improved search on federated tracks list
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Having a powerful but easy-to-use search is important but difficult to achieve, especially
+if you do not want to have a real complex search interface.
+
+Github does a pretty good job with that, using a structured but simple query system
+(See https://help.github.com/articles/searching-issues-and-pull-requests/#search-only-issues-or-pull-requests).
+
+This release implements a limited but working subset of this query system. You can use it only on the federated
+tracks list (/manage/federation/tracks) at the moment, but depending on feedback it will be rolled-out on other pages as well.
+
+This is the type of query you can run:
+
+- ``hello world``: search for "hello" and "world" in all the available fields
+- ``hello in:artist`` search for results where artist name is "hello"
+- ``spring in:artist,album`` search for results where artist name or album title contain "spring"
+- ``artist:hello`` search for results where artist name equals "hello"
+- ``artist:"System of a Down" domain:instance.funkwhale`` search for results where artist name equals "System of a Down" and inside "instance.funkwhale" library
