(cherry picked from commit e3e99d81799fdce7ee18ef091d85529956783ff2)
> Fuzzy query to support prefix length and max expansions
> -------------------------------------------------------
>
> Key: SOLR-17714
> URL: https://issues.apache.org/jira/browse/SOLR-17714
> Project: Solr
> Issue Type: Improvement
> Components: SearchComponents - other
> Reporter: Siju Varghese
> Priority: Major
> Labels: pull-request-available
> Time Spent: 0.5h
> Remaining Estimate: 0h

> Currently solr supports fuzzy query variants with the "~" operator.
> [https://solr.apache.org/guide/6_6/the-standard-query-parser.html]
> Lucene supports prefix length and max expansion parameters for fuzzy query.
> The prefix length parameter is quite useful because it maintains the
> configured prefix from the original token. In the absence of this, a user
> could get undesired results, ex : for foor~1 where the user intended foor to
> get corrected to food, it will correct to door etc,
> It will be a useful feature to have where we can configure these parameters
> per fuzzy query.
>
> For ex, something like this should be possible ( ignore the syntax )
> name:car AND (type:mazde~1,2,10 OR type:totoye~2,3,20)
> where 1,2,10 for mazde means, 1 edit distance keeping 2 characters in prefix
> and max of 10 expansions. For totoye 2 edits, 3 prefix length max 20
> expansions
