Hi Firas,
Thanks for getting back. Now the issue becomes clearer to me. With your given scenario as below:
1. Go to knowledge.autodesk.com
2. Search for "Firas Noori"
There is only screencast in the search result list which is http://autode.sk/2eGbYNS . The reason why this screencast appears is because in the description field, you somehow mentioned your name "Cheers, Firas S. Noori" at the bottom. This string was picked up by the search engine when searching for "Firas Noori". The other screencast as you mentioned in the original topic was not included because there was no sign of similar text in any description field.

Also, thank for your great feedback about the search functionality. I will bring it up to another team so they will consider it later (that search availability/functionality is not a part of screencast team).
For now, 2 workarounds that I can think of for your students to search for all your screencasts AND contributions:
1. You can tag any of your contributions (screencast, articles etc.) with your name at the bottom, like a signature that you did. It will help ensure that contribution will be included in the search query. Can you try to include your name in the description of this screencast http://autode.sk/2faxtH4 to make sure this method work?
2. You can share your contribution link: https://knowledge.autodesk.com/profile/O37DF4A26CA13958 , please stay tuned as we are releasing another version of contribution and profile in a next few day.
Please let me know if you have any questions or other suggestions.
Thank you,
Peter Nguyen
