> Key: JCR-1080
> URL: https://issues.apache.org/jira/browse/JCR-1080
> Project: Jackrabbit
> Issue Type: Improvement
> Components: indexing
> Reporter: Ard Schrijvers
> Priority: Minor
>
> see [1] for the mail thread on this subject
> Since lucene 2.1, not every unique lucene Field results in a seperate .nrm
> files [LUCENE-756: Maintain all norms in a single .nrm file to reduce the
> number of open files and file descriptors for the non-compound index
> format.]. This makes it possible to instead index all different properties in
> jr in one single lucene Field, to index them all seperately. The index format
> will be easier to understand, and some performance gains might be seen.
> Future possible queries might be easier to implement.
> The implementation should be backwards compatible. We have chosen to start to
> do this by testing the index at startup, and if an old format is detected,
> old style indexing and querying will be done.
