Hi, The spell check component's output is not written when sending queries that consist of numbers only. Clients depending on the availability of the spellcheck output need to check if the output is actually there.
This is with a very recent Solr 3.x check out. Is this a feature or a bug? File an issue? Cheers, -- Markus Jelsma - CTO - Openindex http://www.linkedin.com/in/markus17 050-8536620 / 06-50258350
