Subject Detailed file handling on hard disk
Date Fri, 03 Sep 2010 16:05:04 GMT

Hello everybody,

I read the paper Performance
of Compresses Inverted List Caching in Search Engines  and now I am unsure
how Lucene implements its structure on the hard disk. I am using Windos as
OS and therefore I implemented FSDirectory based on 

How is the skipping in the .tis file realized? Do I use metadata at the
beginning of each block too like in the mentioned paper above on page 388
(in the paper the metadata stores informations about how many inverted lists
are in the block and where they start)? 

Because I read in another article that I can seek to the correct position on
the hard drive with the byte address using (which I
can read from .tii-file in "IndexDelta"?).

How do I find the correct position/location for my PostingList/Document?
Do I need information/metadata about the blocks from the underlying file
Or where can I find further informations about this stuff? :)

Best regards
