1. Captions are not always accurate.
Due to most of the captions being auto-generated, they are not always accurate. What can be heard in a video will sometimes be transcribed as something unexpected by Google's caption transcription algorithm. This tends to occur more often in older videos.
2. Not all searches are conclusive.
Sometimes, a certain word or phrase can be broken up in one video's caption track and not in another. This can cause similar search terms to unexpectedly return different results (e.g., "multicrew" and "multi crew" return different results), and in some cases one term might return results while a similar term returns none. If either of these occur, try rephrasing your search to use a different keyword, or to be less specific.
3. Auto-generated captions only have English localization.
Unfortunately, auto-generated captions are not available in languages other than English. If you are interested in volunteering to transcribe caption tracks for another language, contact me and I'll consider all options for adding them to the Starchives database.
Try multiple spellings when searching for a name.
Because "Lorville" is an uncommon word, the caption generator has interpreted it as "lore ville," "loreville," "lor ville," and more at various occasions, so all three of those terms will yield different results. Such is the case for many spoken names, especially if they are uncommon.
Keep the query around three words at most and four characters at least for effective searches.
Caption lines tend to be around 6-12 words long, with the occasional exceptions for fast speakers. Using too many words will yield few results, and using too few characters can yield not only too many results, but also too many captions.
Search without a query to get results without captions.
If you want to find videos without getting the captions and slowing the page down too much, you can search without a query and use the filters to still get specific groups of videos and their other data, such as views and likes.
