Areek Zillur commented on SOLR-5378: ------------------------------------ Thanks! thats awesome. Let me know if you think the patch can be improved in any way! > Suggester Version 2 > ------------------- > > Key: SOLR-5378 > URL: https://issues.apache.org/jira/browse/SOLR-5378 > Project: Solr > Issue Type: New Feature > Components: search > Reporter: Areek Zillur > Assignee: Shalin Shekhar Mangar > Attachments: SOLR-5378.patch, SOLR-5378.patch, SOLR-5378.patch, > SOLR-5378.patch, SOLR-5378.patch, SOLR-5378.patch, SOLR-5378.patch > > > The idea is to add a new Suggester Component that will eventually replace the > Suggester support through the SpellCheck Component. > This will enable Solr to fully utilize the Lucene suggester module (along > with supporting most of the existing features) in the following ways: > - Dictionary pluggability (give users the option to choose the dictionary > implementation to use for their suggesters to consume) > - Map the suggester options/ suggester result format (e.g. support for > payload) > - The new Component will also allow us to have "beefier" Lookup support > instead of resorting to collation and such. (Move computation from query time > to index time) with more freedom > In addition to this, this suggester version should also have support for > distributed support, which was awkward at best with the previous > implementation due to SpellCheck requirements. > Config (index time) options: > - name - name of suggester > - sourceLocation - external file location (for file-based suggesters) > - lookupImpl - type of lookup to use [default JaspellLookupFactory] > - dictionaryImpl - type of dictionary to use (lookup input) [default > (sourceLocation == null ?
