Ferenczi Jim commented on LUCENE-7317:
--------------------------------------
Sorry for the late reply. Yep min=1/max=2B is not a reasonable setting but I
have similar results with min=1/max=20 so I think it is worth investigating.
I opened https://issues.apache.org/jira/browse/LUCENE-7423 which re-implements
the auto prefix in a new PostingsFormat that builds the prefixes in two pass
like the previous implementation. The nice thing is that it avoids the
combinatorial explosion that affected the previous implementation where we
needed to visit all the matching terms for each prefix.
