Here's the function that allows you to search for a video per word or parts of a word, if it's in the title of the video, it's usually about including words relevant to the topic discussed in the video. For example, if you put Kalcker, all the videos in the title carrying this word will be searched and displayed, within each language, you must select the language, if instead of the whole word uses Kalc, it will most likely also have the same result. If you're looking for diseases such as Autism, the same thing will happen.
No matter if you use upper case or lower case letters, we would be grateful if you would let us know if there is a video that exists and you can't find it the same way to add the most common search word in the title, such as diseases, doctors' names, conference names etc. Use the contact form for it. Thank you.
