Say I have many documents, one document may indicate a door opening, another a door closing, each of these has a doorID field.
I would like to write a query that would return all the cases where a door both opened and closed.
There are doors that "just" opened, or "just closed - those are not interesting to me.
I want only open-closed pairs, based on ID.
How would I create that "connection" between both documents in lucene syntax?
