Attachment: LUCENE_6939.patch
Hello [~mikemccand]
Would you mind having a look at this initial patch when you have the chance?
I am keen to making changes if needed especially regarding the backward
compatibility part of the BlenderType.
Thank you very much.
> BlendedInfixSuggester to support exponential reciprocal BlenderType

> Key: LUCENE-6939
> URL: https://issues.apache.org/jira/browse/LUCENE-6939
> Project: Lucene - Core
> Issue Type: Improvement
> Components: modules/spellchecker
> Affects Versions: 5.4
> Reporter: Arcadius Ahouansou
> Priority: Minor
> Labels: suggester
> Attachments: LUCENE_6939.patch

>
> The orignal BlendedInfixSuggester introduced in LUCENE-5354 has support for:
> - {{BlenderType.POSITION_LINEAR}} and
> - {{BlenderType.POSITION_RECIPROCAL}} .
> These are used to score documents based on the position of the matched token
> i.e the closer is the matched term to the beginning, the higher score you get.
> In some use cases, we need a more aggressive scoring based on the position.
> That's where the exponential reciprocal comes into play
> i.e
> {{coef = 1/Math.pow(position+1, exponent)}}
> where the {{exponent}} is a configurable variable.
