Subject Re: MUST operator across grouped documents
Date Tue, 19 May 2015 18:21:51 GMT
I think it is not possible. There is another problem putting everything in one document, we
need also filter by the number of times a user accessed a url in a period of time. The doc
size would be too big. There are other informations we gather too. 
Do you think it is possible to solve this with a custom query?
