This add-on is a search add-on that will make searching AO3 for a primary ship tag, remove search results that do not have the wanted tag as the first relationship tag. If your ship is listed as a focus or in a supporting role, this add-on will help avoid having your ship overwhelmed with search results that don't have the primary tag as the first relationship tag.

I built this add-on after finding myself having to go through the list of stories to find a story about my ship, and then needing to keep switching between ships and tags to check out every story for every ship.

AO3's search page is a very common spot for stories about other ships to be present, so you could end up with a bunch of stories about other ships in your newsfeed, even though your ship is present and tagged, but not in focus.

It's possible you could even get a totally empty page of search results. If this happens, it's likely that you'll be using multiple ship tags, so the search will include any story that has any of your listed ship tags as the first tag.

If your ship is not in focus, it's possible that someone else is writing the story about it. A lot of times, people put their fic's primary ship first and then add secondary ones later, so it's a pretty good heuristic.
