Nicholas, It sounds like you might want to use WordBreakSolrSpellChecker, which gets obscure mention in the wiki. Read through this section: http://wiki.apache.org/solr/SpellCheckComponent#Configuration and you will see some information.
Also, the Solr Example shows how to configure this. See http://svn.apache.org/repos/asf/lucene/dev/branches/branch_4x/solr/example/solr/collection1/conf/solrconfig.xml Look for... <lst name="spellchecker"> <str name="name">wordbreak</str> ... </lst> ...and... <requestHandler name="/spell" ...> ... </requestHandler> Also, I'd recommend you take a look at each parameter in the "/spell" request handler and read its section on the "spellcheckcomponent" wiki page. You probably will want to set many of these parameters as well. You can get a query to return only spell results simply by specifying "rows=0". However, its one less query to just have it return the results also. If there are no results, your application can check for collations and re-issue a collation query. If there are both results and collations returned, you can give the user results with "did-you-mean" suggestions.

So basically, my search engines is used to search local businesses. For example, user could search for "wall mart", here is a typo, I wanna spellchecker to give me Collation for "walmart". My problems are: 1. I use DirectSolrSpellChecker on my BusinessNameField and pass "wall mart" as phrase search, but I can't get collation from the spellchecker. 2. I tried not to pass phrase search, but pass q=Wall AND Mart to force a 100% match, but spellchecker can't give me collation also. I read the documents about spellchecker on Solr wiki, but it's very brief. I'm wondering is there any best practice of spellchecker, I believe it's widely used in the search, right? And I have another idea, I don't know whether it's valid or not. I want to apply spellchecker everything before doing the search, so that I could rely on the spellchecker to tell me whether my search could get result or not. Thanks Nicholas
