Andrzej Bialecki  commented on SOLR-1316:
-----------------------------------------

Jason, did you make any progress on this? I'm interested in this functionality.. I'm not sure tries are the best choice, unless heavily pruned they occupy a lot of RAM space. I had some moderate success using ngram based method (I reused the spellchecker, with slight modifications) - the method is fast and reuses the existing spellchecker index, but precision of lookups is not ideal.

> 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
