Upstream task: https://secure.phabricator.com/T7314
When entering something in the search bar at the top of the page, the results are swamped by commits. Given that the number of commits increases much more sharply than the number of tasks, this will only become worse with time. I would argue this is a poor user experience because most users (and especially new users who have léess experience navigating Phabricator) are interested in commenting at a task or making a bugreport, not in looking at commits; and even experienced users (who are interested in looking at commits) typically use some sort of review dashboard and not fulltext search to find those.
- if possible, set search to filter for tasks by default
- at the very least, the filter should be set when I am in one of the subareas of Phabricator. I.e. when I am in Maniphest (looking at a bug), the search should be limited to bugs; when I am in Diffusion, the search should be limited to commits.
