Re: Wildcard query vs facet.prefix for autocomplete?
Well, option 2 won't do you any good, so speed doesn't really matter. Your response would have a facet count for dam, all by itself, something like int name=damned2/int int name=dame1/int etc. which does not contain anything that lets you reconstruct the title for autosuggest.

Re: Wildcard query vs facet.prefix for autocomplete?
But I did run across an idea a while ago... Either with a custom update processor or on the client side, you permute the title so you index something like: Shadows of the Damned of the DamnedShadows the DamnedShadows of DamnedShadows of the Index these with KeywordTokenizer and LowercaseFilter. Now, your responses from TermComponent (prefix) contain the entire string and you can display them correctly by rearranging the string at the client side based on the (or whatever delimiter). Still an issue with proper capitalization though since TermsComponent only looks at the actual indexed data and it'll be lower-cased. You could use String, but then you're counting on the user to capitalize properly, always a dicey call. And TermsComponent is very fast FWIW Erick On Wed, Jul 18, 2012 at 9:21 AM, santamaria2 aravinda@contify.com wrote: Well silly me... you're right.

Maybe try EdgeNgramFilterFactory http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters/#solr.EdgeNGramFilterFactory On Mon, Jul 16, 2012 at 6:57 AM, santamaria2 aravinda@contify.comwrote: I'm about to implement an autocomplete mechanism for my search box. I've read about some of the common approaches, but I have a question about wildcard query vs facet.prefix. Say I want autocomplete for a title: 'Shadows of the Damned'. I want this to appear as a suggestion if I type 'sha' or 'dam' or 'the'. I don't care that it won't appear if I type 'hadows'.
