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) http://lucene.472066.n3.nabble.com/PostingsEnum-for-documents-that-does-not-contain-a-term-td4349482.html I found EverythingEnum class in the Lucene50PostingsReader.java, 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.

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 Claude
