Change Details

When users search on flow we may not able to provide results immediately, showing a loading indicator will communicate the user that the request is being processed. The idea is to show an indeterminate loader in the place where the counter of matches will appear to communicate that those are being calculated. Search controls will be visible, and while navigation ones will be disabled, the close one will be active to cancel the search. {F167522} Check [[ https://phabricator.wikimedia.org/T75972#834246 | more details on the indeterminate loader ]]
