Re: Using autocomplete with the new Suggest component
Hi Victor, I have the same questions about the new Suggest component. I can't really help you as I didn't really manage to understand how it worked. Sometimes, I had more results, sometimes less. Even so, I would really be interested in your resources using Terms and shingles to implement auto-complete. I am myself a French student and it could help me improve the solution of one of my project.

Re: Autocomplete(terms) middle of words
You can do it without NGram with a query like this : http://localhost:8983/solr/terms?terms=true&terms.fl=suggestionField&terms.regex=(.*)chest(.*)&terms.regex.flag=case_insensitive In my case, I had to encode (.*) so replace it with %28.*%29 if needed. It use a regex. I don't know if it has an impact on performance. 2011/4/29 lboutros > you could use EdgeNGramFilterFactory : > > > http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters#solr.EdgeNGramFilterFactory > > And you should mix front and back ngram process in your analyzer : > > maxGramSize="15" > side="front"/> > maxGramSize="15" > side="back"/> > > is it better ? > > Ludovic. > -Jouve > France.-- > View this message in context: > http://lucene.472066.n3.nabble.com/Autocomplete-terms-middle-of-words-tp2878694p2878891.html > Sent from the Solr - User mailing list archive at Nabble.com. > -- Quentin Proust Email : q.pro...@gmail.com Tel : 06.78.81.15.94 http://www.linkedin.com/in/quentinproust
Re: Autocomplete(terms) middle of words
@roySolr : terms.regex exits from Solr 3.1. Doesn't seem compatible. @ramires : Did you try with space in your regex. Something like terms.regex=(.*) book (.*) <-- I put space before and after book. If it doesn't work, try to replace space with %20. I didn't try so I don't know if it work. 2011/4/29 roySolr > terms.regex doesn´t work for me. Prefix works fine. I use SOLR 1.4..
