What do you suggest I could work on now? Some time ago I added comments on the performance of my change on github. I wondered whether I should try to replace “NOT IN” with “NOT EXIST” (it would be faster then, but I found it not easy to do with active records), choose a completely different way of implementing the feature or leave it as it is. There’s also the new issue connected with search: [Include translated posts in search?](https://meta.discourse.org/t/include-translated-posts-in-search/83589), so maybe I could take a look at it in the meantime?
