spell check vs terms component
Hi, We are trying to implement auto suggest feature in our application. I would like to know the difference between terms vs spell check component. Both the handlers seems to display almost the same output, can anyone let me know the difference and also I would like to know when to go for spell check and when to go for terms component.

SpellCheckComponent is designed to operate on whole words and not partial words so I don't know how well it will work for auto-suggest, if at all. As far as differences between SpellCheckComponent and Terms Component is concerned, TermsComponent is a straight prefix match whereas SCC takes edit distance into account. Also, SCC can deal with phrases composed of multiple words and also gives back a collated suggestion. -- Regards, Shalin Shekhar Mangar.

An alternative to using the SpellCheckComponent and/or the TermsComponent, would be the (Edge)NGrams filter. Basically, this filter breaks words down into auto-suggest-friendly tokens (i.e., Hello = H, He, Hel, Hell, Hello) that works great for auto suggestion querying. Here is an article from Lucid Imagination on using the ngram filter: http://www.lucidimagination.com/blog/2009/09/08/auto-suggest-from-popular-queries-using-edgengrams/ Here is the SOLR wiki entry for the filter: http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters#solr.EdgeNGramFilterFactory - Ken Stanley
