----------------------------------
Resolution: Done
> Implement script to compare lucene indexes logically
> ----------------------------------------------------

> Key: OAK-7122
> URL: https://issues.apache.org/jira/browse/OAK-7122
> Project: Jackrabbit Oak
> Issue Type: Task
> Components: run
> Reporter: Chetan Mehrotra
> Assignee: Chetan Mehrotra
> Fix For: 1.8
>
>
> With Document Traversal based indexing we have implemented a newer indexing
> logic. To validate that index produced by it is is same as one done by
> existing indexing flow we need to implement a script which can enable
> comparing the index content logically
> This was recently discussed on lucene mailing list [1] and suggestion there
> was it can be done by un-inverting the index. So to enable that we need to
> implement a script which can
> # Open a Lucene index
> # Map the Lucene Document to path of node
> # For each document determine what all fields are associated with it (stored
> and non stored)
> # Dump this content in file sorted by path and for each line field name
> sorted by name
> Then such dumps can be generated for old and new index and compared via
> simple text diff
