[ http://issues.apache.org/jira/browse/SOLR-81?page=comments#action_12460397 ] Erik Hatcher commented on SOLR-81: ----------------------------------
The way the spell checker works is to have a separate spell checking index. This could be integrated into Solr with a custom cache that builds the dictionary index into a RAMDirectory. I've done this in Collex for AJAX suggestions. Will it scale? I'm not sure, but I suspect for many Solr installations it'd fit into RAM just fine. Tie in a custom request handler (and underlying Util class like highlighting, etc) and you're all set! :) What have I overlooked or oversimplified? > Add Query Spellchecker functionality > ------------------------------------ > > Key: SOLR-81 > URL: http://issues.apache.org/jira/browse/SOLR-81 > Project: Solr > Issue Type: New Feature > Components: search > Reporter: Otis Gospodnetic > Priority: Minor > Attachments: SOLR-81-ngram.patch > > > Use the simple approach of n-gramming outside of Solr and indexing n-gram > documents.
