Subject [jira] [Created] (LUCENE-3306) disable positions for spellchecker ngram fields
Date Tue, 12 Jul 2011 17:21:00 GMT
disable positions for spellchecker ngram fields

                 Key: LUCENE-3306
             Project: Lucene - Java
          Issue Type: Improvement
            Reporter: Robert Muir
             Fix For: 3.4, 4.0

In LUCENE-2391 we optimized spellchecker (re)build time/ram usage by omitting frequencies/positions/norms
for single-valued fields,
among other things.

Now that we can disable positions but keep freqs, we should disable them for the n-gram fields,
because the spellchecker does
not use positional queries.
