Following up on this post: Are specific terms ignored from searches?
I recently ran into this problem when a moderator was trying to find the “About” post in a specific category. They had unpinned the post. Searching for just the word “about” gave no results, but searching for “about the x category” gave the exact post.
This seems like such a simple thing to fix and such an obvious problem. How many Discourse categories must there exist in the world that have an “About” post and they are all unsearchable.
