The value of the extraParams property is appended to the query string of the data URL. So whatever parameters you put in extraParams they end up as request parameters for live table data. Some are handled by XWiki.LiveTableResults (space, parent, orphaned) and others may be handled by XWiki.LiveTableResultsMacros. In any case there's no general rule on how the "extra" parameter is used. extraParams is basically just a way to pass additional parameters to the live table data URL. If you're interested in a particular parameter then you need to check how it is used in the live table code to see if it accepts complex values/expressios with operators like the ones you listed.
