             Summary: FingerprintFilter - a TokenFilter for clustering/linking purposes
                 Key: LUCENE-6747
                 URL: https://issues.apache.org/jira/browse/LUCENE-6747
             Project: Lucene - Core
          Issue Type: New Feature
          Components: modules/analysis
            Reporter: Mark Harwood
            Priority: Minor


A TokenFilter that emits a single token which is a sorted, de-duplicated set of the input
tokens.
This approach to normalizing text is used in tools like OpenRefine[1] and elsewhere [2] to
help in clustering or linking texts.
The implementation proposed here has a an upper limit on the size of the combined token which
is output.
