[jira] [Created] (LUCENE-5318) Co-occurrence counts from Concordance

Tim Allison created LUCENE-5318:
-----------------------------------

             Summary: Co-occurrence counts from Concordance
                 Key: LUCENE-5318
                 URL: https://issues.apache.org/jira/browse/LUCENE-5318
             Project: Lucene - Core
          Issue Type: New Feature
          Components: core/search
    Affects Versions: 4.5
            Reporter: Tim Allison
             Fix For: 4.6
         Attachments: cooccur_v1.patch.gz

This patch calculates co-occurrence statistics on search terms within a window of x tokens.  This can help in synonym discovery and anywhere else co-occurrence stats have been used.

The attached patch depends on LUCENE-5317.

Again, many thanks to my colleague, Jason Robinson, for advice in developing this code.
