This is great, I've been looking for exactly that! Often times there are "hidden gems" of knowledge in longer videos, for example how some calculations for a specific problem are done when the rest of the video has a different topic. I found it very hard to look for these hidden gems.

My test example for such a soltion would be: "does it find the chapter about thermal calculations in a video about electronics": https://youtu.be/8xX2SVcItOA?feature=shared&t=758

How do I add a video? I'd love to test your solution with this video.

Thanks for making the source available too! I've been trying to build something similar with jupyter notebooks, but I keep getting stuck at this "hidden gem" problem.

Hey there! Thanks a lot :) I've gone ahead and indexed the video you shared and you can try searching something like: "how does heat sink thermal calculation work" as it tends to work better with question.

You could also add more videos by clicking on the hamburger menu on the right of the search bar and click on "Index videos". However, you'll need to do a quick email sign up and you can index as many videos as you like!

Yeah the "hidden gem" problem is a difficult one to solve and I think with the current tech out there, we are getting a step closer with better solutions. The search engine still has a lot of work to be done especially for broader queries & improving accuracy.

Would love to see how the community can build on this!

Thank you for answering and indexing the video so quickly.

I'm blown away how good this works! I searched for the query just like you said and it really found exactly the relevant section of the video. Very impressive!

You're right, the query seems to be very sensitive to the exact phrasing. Searching for "heat sink thermal calculation" results in nine videos, (the wanted one on fifth place at least), while your query seems more targeted. "calculate heat sink power dissipation" works reasonably well too.

So again - wow. This is really great and exactly what I've been trying to build for myself too.

One really useful feature for me would be inclusion/exclusion of channels in the search results. For this example, when I'm specifically looking for calculations, I can probably skip channels like LTT from the search results.

Thanks for this amazing tool!

It doesn't sound ideal that it's so phrasing dependant - 5th on a list of 9 videos is poor if you're searching without knowing which video you're looking for and without knowing the best search phrase to use - unless those 4 above it actually also answer the same thing?

Is it random luck which phrases work best, or is it in a way that a frequent user of the service could learn the good and bad ways to structure a query (and/or can it be tweaked so that all queries work well)?

(Questions aimed at the world generally, not specifically at the person I'm replying to.)

Technically the other videos do talk about the above query, just that not enough videos of it have been indexed to produce a better result.

While yes promoting/querying tends work better in questions based on how its built, I've been exploring more ways by mixing full text fuzzy search along with the current method to allow for broader queries as well :)
