Otis Gospodnetic updated LUCENE-1417:
-------------------------------------
Priority: Minor (was: Major)
I agree with Grant. I like that we not have pluggable distance metric, for
example.
> Allowing for distance measures that incorporate frequency/popularity for
> SuggestWord comparison

> Key: LUCENE-1417
> URL: https://issues.apache.org/jira/browse/LUCENE-1417
> Project: Lucene - Java
> Issue Type: Improvement
> Components: contrib/spellchecker
> Affects Versions: 2.4
> Reporter: Jason Rennie
> Priority: Minor
> Original Estimate: 4h
> Remaining Estimate: 4h
>
> Spelling suggestions are currently ordered first by a string edit distance
> measure, then by popularity/frequency. This limits the ability of
> popularity/frequency to affect suggestions. I think it would be better for
> the distance measure to accept popularity/frequency as an argument and
> provide a distance/score that incorporates any popularity/frequency
> considerations. I.e. change StringDistance.getDistance to accept an
> additional argument: frequency of the potential suggestion.
> The new SuggestWord.compareTo function would only order by score. We could
> achieve the existing behavior by adding a small inverse frequency value to
> the distances.
