[DOC] Search fields - Content in relations - Foreign tables

Feature Request

Is your feature request related to a problem? Please describe. The clear relationship between tables doesn't seem to be clear for the search.fields plugin setting. Let's say I want to be able to search Content Elements' content associated to news. Based on current documentation, it would seem that content_elements.bodytext is the solution. After some observations, it would appear not to work. At this point, you could go through tables and find references to foreign tables such as tt_content or other keys such as tx_news_related_news, but it still wouldn't be clear which path is needed to get to the core idea of searching the text part of Content Elements.

Describe the solution you'd like The documentation could use some improvements: I believe putting an example with foreign tables would help clear the subject for future users. The same way categories.title is popular enough to warrant an example, I believe Content Elements' content as base is worth a shot.

Teachability, Documentation, Adoption, Migration Strategy I believe an explanation of links between tables with the above example would be enough as base documentation.

I pushed some changes. contentElements.header is the correct code
