Query the doc frequency across multiple search field.

2016-07-19 Thread Xiaolong Zheng 
Hi,

I want to know is there any way that query the doc frequency across
multiple search field?

The existing API seems only provide the query for a single search field:


  indexReader.docFreq(new Term(field, word))


Any suggestions that I could get the doc frequency from multiple field?

Thanks in Advance,

​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.
