Subject [jira] Updated: (SOLR-1316) Create autosuggest component
Date Thu, 27 May 2010 22:10:00 GMT


Andrzej Bialecki  updated SOLR-1316:

    Attachment: SOLR-1316.patch

Updated patch - previous version had a missing "else" in TSTLookup.

Improved benchmark - the other results are useless, the running time was too short. Also,
this time the lookup keys are strict prefixes between 1/3 and 1/2 length of the key.  Result
counts are cross-validated between JaSpell and TST implementations.

Here are the new timings (times in [ms] for 100k items):

> Autosuggest is a common search function that can be integrated
> into Solr as a SearchComponent. Our first implementation will
> use the TernaryTree found in Lucene contrib. 
> * Enable creation of the dictionary from the index or via Solr's
> RPC mechanism
> * What types of parameters and settings are desirable?
> * Hopefully in the future we can include user click through
> rates to boost those terms/phrases higher
