Subject Re: What is the fastest way to loop over all documents in an index?

Hi Jean,

I am also interested answers to this question. I need this feature too. Currently I am using
a hack.
I create an artificial field (with an artificial token) attached to every document. 

I traverse all documents using the code snippet given in my previous related question. (no
one answered to it)
I found EverythingEnum class in the, but I couldn't figure out
how to use it.
So, I do not know if this class is for the task, but its name looks promising.

Hi there,

I have an use case, were I need to iterate over all documents in an index from time to time.
It seems that the MatchAllDocsQuery is what I should use for this, however it creates a bunch
of Objects (Score etc) that I don’t really need.

My question to you is: 

What is the fastest way to loop over all documents in an index?
Is it looping over all possible doc id’s (+filtering out deleted documents)?

Thank you very much.

Best regards
