Thanks for the quick reply. However, I'm still not able to setup
spellchecker. Solr does create spell directory under data but doesn't seem
to build the spellchecker index. Here are snippets of my schema.xml:
<field name="title" type="string" indexed="true" stored="true"/>
<requestHandler name="spellchecker" class="solr.SpellCheckerRequestHandler"
startup="lazy">
<!-- default values for query parameters -->
<lst name="defaults">
<int name="suggestionCount">1</int>
<float name="accuracy">0.5</float>
</lst>
<!-- Main init params for handler -->
<!-- The directory where your SpellChecker Index should live. -->
<!-- May be absolute, or relative to the Solr "dataDir" directory. -->
<!-- If this option is not specified, a RAM directory will be used -->
<str name="spellcheckerIndexDir">spell</str>
<!-- the field in your schema that you want to be able to build -->
<!-- your spell index on. This should be a field that uses a very -->
<!-- simple FieldType without a lot of Analysis (ie: string) -->
<str name="termSourceField">title</str>
</requestHandler>
I tried this url:
http://localhost:8984/solr/select/?q=Accountent&qt=spellchecker&cmd=rebuildand
receive this:
<response>
<lst name="responseHeader">
<int name="status">0</int>
<int name="QTime">2</int>
</lst>
<str name="cmdExecuted">rebuild</str>
<arr name="suggestions"/>
</response>

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
