Content of Wiki Pages as column in my LiveTable


I am new in this forum and as a user of XWiki. I am using the wiki as a knowledge database. At the moment the wiki is growing and the information are getting more and more difficult to find. Therefore, I am using a livetable to filter my Wiki based on the tags which works fine and I am getting the wiki pages that I want.
Nevertheless, I would like to show some keywords (which I don’t want to create as tags) in the livetable as well. E.g. On every page that I want to filter, there is a keyword like “Business field: automotive” and I would like to have the word that come behind the keyword (“automotive” it in a column of my livetable “business field”.
Is that possible only with scripting privilegdes? Or do I have to use the tags as well

Thanks a lot in advance!
