I upgrade lucene to 6.1.0, hope it works, thank you very much!
the mount( contain all data directories and index directories ) is shared
by four different computers, but each index directory can be accessed only
by one computer, we have four index directories.

Hi Adrien, I had a chance to test and I see that there is one more
solution. For fields that we want to search for exist/doesn't exist add one
more indexed field, like "ex_field=1" and can search by: +ex_field=1 or
-ex_field=1. It works fast.

Hello.
I want to set LMJelinekMercer Similarity (with lambda set to, say, 0.6) for
the Luke similarity calculation. Luke by default use the DefaultSimilarity.
Can anyone help with this? I use Lucene 4.10.4 and Luke for that version
of Lucene index.
Dwaipayan..
Note that if you only have two fields A and B, you could make it faster by
returning `docFreq(A)+docFreq(B)-IndexSearcher.count(A AND B)` rather than
`IndexSearcher.count(A OR B)` since Lucene is typically faster at running
conjunctions than disjunctions.

Thanks! The use case that I am having is I am trying to calculate the
docFreq for the suggestion word which produced by my "did you
mean"/"spellcheck" feature.
I was trying to avoid to having a second search request. But it seems in
this case, I have to formula another search query to do the job.
There is no way to get this statistic in constant-time. If you need it for
scoring, you need to make approximations. For instance, BlendedTermQuery
uses the max of the doc freqs as the aggregated doc freq.
Otherwise, you can also compute this number by running a BooleanQuery with
one SHOULD clause
I use ubuntu to run lucene(java8, lucene6.0.0, not ES), and nfs to mount
disk(actually is rocketstor) of macmini. I get this error constantly. I
have already used org.apache.lucene.index.CheckIndex, but will still crash
after restart program.
