Walter Underwood created LUCENE-4810:
----------------------------------------
Summary: Positions are incremented for each ngram in
EdgeNGramTokenFilter
Key: LUCENE-4810
URL: https://issues.apache.org/jira/browse/LUCENE-4810
Project: Lucene - Core
Issue Type: Bug
Components: modules/analysis
Reporter: Walter Underwood
Edge ngrams should be like synonyms, with all the ngrams generated from a token
having the same position as that original token. The current code increments
position.
For the text "molecular biology", the query "mol bio" should match as a phrase
in neighboring positions. It does not.
You can see this in the Analysis page in the admin UI.
