The spellchecker should be available in 1.2 release, your query is incorrect, try the following:
http://localhost:8984/solr/select/?q=java&qt=spellchecker&termSourceField=title_text&cmd=rebuild the 'q' parameter must only contain the word being checked; you must specify the field separately. You can set "termSourceField" in your solrconfig.xmlfile so you do not need to explicitly set it each time you want to run a spell check query. Also make sure your field isn't heavily processed (i.e. with porter stemmer analyzers) otherwise the suggestions will look a bit weird / mangled. Take a look at the wiki page for more info: http://wiki.apache.org/solr/SpellCheckerRequestHandler cheers, Tristan On 7/9/07, climbingrose <[EMAIL PROTECTED]> wrote:
Hi Tristan, Is this spellchecker available in 1.2 release or I have to build the trunk. I tried your instructions but Solr returns nothing: http://localhost:8984/solr/select/?q=title_text:java&qt=spellchecker&cmd=rebuild Result: <response> <lst name="responseHeader"> <int name="status">0</int> <int name="QTime">3</int> </lst> <str name="cmdExecuted">rebuild</str> <arr name="suggestions"/> </response> Thanks.
