Ankul Garg commented on SOLR-1316:

Here are the results comparing TSTLookup for UnsortedTFIT and SortedTFIT:

TSTLookup:	buildTime=358	lookupTime=420
TSTLookup:	buildTime=359	lookupTime=418
TSTLookup:	buildTime=356	lookupTime=361

The lookup time in second case seems to have further reduced with a slight overhead for build

> 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
