Bill Bell commented on SOLR-7539: --------------------------------- +1 > Add a QueryAutofilteringComponent for query introspection using indexed > metadata > -------------------------------------------------------------------------------- > > Key: SOLR-7539 > URL: https://issues.apache.org/jira/browse/SOLR-7539 > Project: Solr > Issue Type: New Feature > Reporter: Ted Sullivan > Priority: Minor > Fix For: Trunk > > Attachments: SOLR-7539.patch, SOLR-7539.patch, SOLR-7539.patch > > > The Query Autofiltering Component provides a method of inferring user intent > by matching noun phrases that are typically used for faceted-navigation into > Solr filter or boost queries (depending on configuration settings) so that > more precise user queries can be met with more precise results. > The algorithm uses a "longest contiguous phrase match" strategy which allows > it to disambiguate queries where single terms are ambiguous but phrases are > not. It will work when there is structured information in the form of String > fields that are normally used for faceted navigation. It works across fields > by building a map of search term to index field using the Lucene FieldCache > (UninvertingReader). This enables users to create free text, multi-term > queries that combine attributes across facet fields - as if they had searched > and then navigated through several facet layers. To address the problem of > exact-match only semantics of String fields, support for synonyms (including > multi-term synonyms) and stemming was added. -- 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
