Broken/useless search

This is with the GNOME instance (https://gitlab.gnome.org).

Steps: a) open this page b) type in the "Search or filter results" text: 2.26 c) press Enter

Only 4 issues are shown (in the All section), but for example this issue contains the 2.26 string 10 times, and it's not picked by the GitLab search.
