Backend for Lucene format indexes-How to get doclength
Hi, all:
I have wrote a demo patch for Backend for Lucene format indexes, Lucene
version is 3.6.2.
http://lucene.apache.org/core/3_6_2/fileformats.html
Now, this demo patch just support the basic features in Lucene. Compound
File(.cfs/.cfe)?term vector(.tvx/.tvd/.tvf)
delete document(.del) are not supported, skip list in .fdx is not supported
too
example/quest.cc is used to test this demo.
