Andrzej Bialecki updated SOLR-1316:
------------------------------------
Attachment: suggest.patch
This is a very much work in progress, to get review before proceeding.
Highlights of this patch:
* created a set of interfaces in o.a.s.spelling.suggest to hide implementation
details of various autocomplete mechanisms.
* imported sources of RadixTree, Jaspell TST and Ankul's TST. Wrapped each
implementation so that it works with the same interface. (Ankul: I couldn't
figure out how to actually retrieve suggested keys from your TST?)
* extended HighFrequencyDictionary to return TermFreqIterator, which gives not
only words but also their frequencies. Implemented a similar iterator for
file-based term-freq lists.
> Create autosuggest component

> 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
