What is it?

Bilibili Search Purify is a browser userscript for Tampermonkey that cleans up Bilibili's search results pages. When a search returns videos whose titles do not contain the search keywords, the script hides them, which targets the unrelated recommendations that often appear in search results.

Beyond keyword matching, the script applies a built-in set of regular-expression blocklists covering suggestive content, exaggerated clickbait titles, and meaningless memes. Blocked UP uploaders can also be filtered by name. Filtering runs as the page renders, using requestAnimationFrame together with a MutationObserver, so matching videos are removed without briefly flashing on screen. It also keeps working through Bilibili's infinite scroll and pagination.

To customize the filters, you edit the BLACKLIST_WORDS regex array and the BLACKLIST_UP_NAMES list inside the script in the Tampermonkey dashboard. The script is distributed through GreasyFork and released under the MIT license.
