If you are saying that you want to change highlighting behaviour, not query behaviour, then I suspect you are going to have to interact with the java HighlightComponent. If you can work out how to update that component to behave as you wish, you could either subclass it, or create your own implementation that you can include in your Solr setup. Or, if you make it generic enough, offer it back as a contribution that can be included in future Solr releases.
