Summary: 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 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
