Ankul Garg commented on SOLR-706: --------------------------------- I got some benchmarking results comparing lucene's prefix search and autocomplete by trie using hashMap at each node (roughly a TST or even better). TST works much better than lucene's prefix search. How about using it in Solr? > Fast auto-complete suggestions > ------------------------------ > > Key: SOLR-706 > URL: https://issues.apache.org/jira/browse/SOLR-706 > Project: Solr > Issue Type: New Feature > Components: search > Reporter: Shalin Shekhar Mangar > Assignee: Shalin Shekhar Mangar > Fix For: 1.5 > > > A lot of users have suggested that facet.prefix in Solr is not the most > efficient way to implement an auto-complete suggestion feature. A fast > in-memory trie like structure has often been suggested instead. This issue > aims to incorporate a faster/efficient way to answer auto-complete queries in > Solr. > Refer to the following discussion on solr-dev -- > http://markmail.org/message/sjjojrnroo3msugj -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
