[ http://issues.apache.org/jira/browse/SOLR-81?page=comments#action_12460331 ] Otis Gospodnetic commented on SOLR-81: --------------------------------------
Ogün - yes, that Spellchecker class in Lucene's contrib/spellchecker has 1.0f defined as the boost for the last n-gram. I'm not even sure if that's needed. I talked to Bob Carpenter (alias-i.com) about it recently, and he said boosting the end ngram doesn't make sense, if I remember correctly. I'm inclined to go remove that from the source completely. Thoughts? I'm unsure about how to integrate the Lucene spellchecker code into Solr, though. There is no "n-gram tokenizer" per se in the spellchecker extension, so I can't really point NGramFilter config in Solr's schema.xml to anything in that spellchecker library.... I can write my own n-gram Filter, that's not a problem, but you said you made use of the Lucene spellchecker code, and I can't see how to do that. Did you simply create your own NGramFilter that creates the same ngrams as Spellchecker.java, and then used the Spellchecker.suggest(String word) method *only* for fetching/getting alternative spelling suggestions? > 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 > > Use the simple approach of n-gramming outside of Solr and indexing n-gram > documents.
