Silvan Zurbruegg commented on SOLR-1316:
----------------------------------------

Is there a possibility to have minimal query-logic when looking up suggestions with the suggester?
Afaik, all syntax like 'AND' or 'OR' is stripped by the QueryConverter. From playing around with the suggester i figured out that looking up multiple terms is possible, resulting in a 'OR'-like list for each term. Is it possible to have support for an 'AND' logic as well? For example looking up the terms '+css' and '+web' would yield in suggestions from documents that contain both terms. The first thing coming to mind are TermVectors, but since term vectors are document based and probably not related to the suggester-dictionary this could get complicated and is probably out of the scope of the suggester 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
