Hello @
heynana
Firstly a minor housekeeping issue... You already have a thread that asks a similar question. Please just use that thread for your MMA questions. It allows moderators to keep track of our answers without searching and, more importantly, all the answers are in one place so other members can easily find information on MMA. So I will merge this post into your other thread.
If you want to be able to search actors, then the actors/fighters need to be included at the TV Show level, not only the Episode level. Have a look at the TV Show NFO Files here...

If you look at Section 4 there are sample NFO Files. The TV Show NFO File holds actors at the TV Show level, and can be used for search. The Episode NFO File also holds actors details, but won't be used in search results.
How this is scraped depends upon how the Scraper site has entered the information.
The easiest way to move episode actors/fighters to the tv show level is...
1. Export your library to separate NFO Files...

2. Edit the TV Show NFO and include the required actors/fighters into the TV Show nfo file
3. Refresh the TV Show. No need to refresh the Episodes...
