Hi, I think you can use SpanQueries to do this! See: https://lucene.apache.org/core/6_2_0/core/org/apache/lucene/search/spans/package-summary.html
I have no closely looked into your problem, but you should be able to combine those queries. Alternatively subclass one of the classes to do additional position checks.
