Probably you also need to add in bytes lost to alignment requirements,

Thanks for your quick answers.

Cool, yeah separating the DocumentsWriter into multiple classes
certainly helped understanding the complex code better.

Hi Michael,
I've actually been working on factoring DocumentsWriter, as a first
step towards flexible indexing.
I agree we would have an abstract base Posting class that just tracks
the term text.
Then, DocumentsWriter manages inverting each field, maintaining the
per-field hash of term Text ->
11 matches
