can't use distributed spell check

[Li Li]

hi all,
    I tested it following the instructions in
http://wiki.apache.org/solr/SpellCheckComponent. but it seems something
wrong.
     the sample url in the wiki is

http://solr:8983/solr/select?q=*:*&spellcheck=true&spellcheck.build=true&spellcheck.q=toyata&qt=spell&shards.qt=spell&shards=solr-shard1:8983/solr,solr-shard2:8983/solr
    It can't work and I read the codes, it seems qt=/spell shards.qt=/spell
    After I modified the url, it search all the documents but without any
spell suggetions. I debuged it and found the method getSuggestions() in
AbstractLuceneSpellChecker are called.
