[jira] [Commented] (LUCENE-5172) FuzzySuggester should boost terms with minimal Levenshtein Distance

    [ https://issues.apache.org/jira/browse/LUCENE-5172?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16889047#comment-16889047 ]

>                 Key: LUCENE-5172
>                 URL: https://issues.apache.org/jira/browse/LUCENE-5172
>             Project: Lucene - Core
>          Issue Type: Improvement
>          Components: modules/other
>    Affects Versions: 4.4, 4.3.1
>            Reporter: Anna Björk Nikulásdóttir
>            Priority: Major

> For my use case I need both suggesters: AnalyzingSuggester and FuzzySuggester because FuzzySuggester does not boost terms with minimal Levenshtein distance. 
> Post processing of FuzzySuggester results is somewhat heavy if only one wants to find direct prefix suggestions. So I first use AnalyzingSuggester to find prefix suggestions and optionally FuzzySuggester afterwards if AnaylzingSuggester did not yield appropriate results.
> It would be really useful if FuzzySuggester could boost/sort suggestion results in order of Levenshtein distances. Then I only would need FuzzySuggester.
