Great! One comment: if I type a word that happens to be real, it may not be what I actually want. A spell checker should still recommend similar words.
Computer programmers are all perfect spellers, and this can blind us to what matters to ordinary people :) Lance Norskog -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Monday, October 08, 2007 8:27 AM To: solr-user@lucene.apache.org Cc: Otis Gospodnetic Subject: Re: Spell Check Handler Greetings, I too have a strong need to handle multiple words. Also I have run in to a limitation within the current SpellCheckerRequestHandler where it does not identify if a word is spelled correctly or not. This is a problem, for if there are no suggestions, one cannot currently tell if the word is spelled correctly, or if there are just are no matches in the index. I have made modifications to the SpellCheckerRequestHandler source code to handle all of these issues. It reports if a word is correctly spelled or not, and it can handle multiple words too. The nice thing is that it should NOT "break" current implementations are are using it the way it currently exists. I am also wanting to ensure the design format of how the SpellCheckerRequestHandler plays well with other technologies such as Prototype. I am in the process of making significant changes to our application and I have not been able to fully write the interface to utilize these new spelling features, so as such, I was hesitant to make any posts in this area. I was wanting to fully test these changes to ensure their optimal functionality and structure before I said anything on this thread or the developer's thread. If you like, I can post the source code changes that I made to the SpellCheckerRequestHandler, but at this time I am not ready to open a JIRA issue and submit the changes back through the subversion. I will need to do a little more testing, documentation, and create some unit tests to cover all of these changes, but what I have been able to perform, it is working very well. Please let me know if you would like me to explain at a higher level what these changes are and how the output will look. I personally would like some feedback, but right now (Monday AM) I am pressed for time. This afternoon I could give you some examples of how these changes look under the "standard" format and the multi-word formats. One area that I was wanting to really include with the documentation, is how they can be utilized with Prototype using the JSon output type. As I stated earlier, I have not had a chance to write the code yet, but I am thinking that with utilizing Prototype's AJax support with Solr and the JSon output type, one should be able to get a great deal of functionality with very few lines of code. Anyway, let me know if you want me to expand on any of these subjects and I should be able to get back with you this afternoon. If you are wanting me to create a jar so you to play with these changes, let me know and I can email it directly to you.

I'm referring to the change to the SpellCheckerRequestHandler to handle spelling corrections/suggestions for multi-word queries. Any chance you can provide a patch? Thanks!
