Subject Re: Wrong ID in explain() method.
Date Fri, 29 Dec 2017 06:25:59 GMT
If I check

GET myindex/mytype/342

Nothing is found.

I suppose there is a name conflict and Lucene erroneously finds "id" of
a nested object (category from a list) and erroneously assumes that it is
an ID of a whole document.

Is that possible? Is "id" string is reserved word for Lucene?
