A way to do advanced search for anime based on the source?

Here are some tips for doing advanced searches to find anime based on the source material:

• Use sites like MyAnimeList or Anime-Planet that allow searching by source work. You can search for anime adapted from specific manga, novels, games, etc.
  
• On streaming sites like Crunchyroll or VRV, use quotes around the source title to search for anime adaptations. For example "Attack on Titan" to find anime based on the manga.
  
• Search databases like Anime News Network or AniDB using filters for source work, adapted from, and related adaptations. Useful for finding different versions of the same franchise.
  
• Google with site filters can also work. For example: "yakuza anime" site:myanimelist.net finds anime adapted from the Yakuza games.
  
• Leverage sites like Reddit, Wikipedia, and fandom wikis to find lists of adaptations from a specific source work. Useful for comprehensive searches.
  
• Follow creators, studios, and publishers to stay updated on new anime adaptations they announce from existing popular works.
  
• Check out seasonal anime previews that highlight upcoming adaptations each season and link back to the source material.
  

The key is using databases that index the source work information and leveraging search operators and filters. Taking advantage of anime knowledge bases can help surface adaptations you may have missed.
