Hmm, if I add:
<lst name="spellchecker">
<str name="classname">solr.FileBasedSpellChecker</str>
<str name="name">file</str>
<str name="sourceLocation">spellings.txt</str>
<str name="characterEncoding">UTF-8</str>
<str name="indexDir">./spellcheckerFile</str>
</lst>
To the examples declaration with the spellings.txt in the working
directory, it works for me.
Did you see any exceptions in your log?

I'm playing with the new code checked in under SOLR-572 (compliments
to everyone who worked on that!) and am having a couple of problems.
I'm running on Windows under Tomcat 5.5.25.
1. Just in comparison with the old SpellCheckerRequestHandler
methodology, when I specified in solrconfig.xml
<str name="sp.dictionary.indexDir">spell</str>
it built the spelling index under my solr/data directory as
c:/solr/data/spell. My solr home is configured in server.xml for
tomcat via:
<Context ... <Environment name="solr/home" type="java.lang.String"
value="C:/solr" override="true" /> </Context>
Under the new handler, setting the analogous (I think) parameter
<str name="spellcheckIndexDir">spell</str>
drops the spell index directory in my tomcat install directory
C:/Program Files/Apache Software Foundation/Tomcat 5.5/spell rather
than my solr/data. Should I configure my solr/home differently or can
this be made to work as before? The previous solr/data default on an
unqualified parameter value was a good one for keeping the index files
in the same location.
2. I'm having difficulty getting the FileBasedSpellChecker to work --
probably something silly on my part but given the above I thought
there might be container differences that haven't been vetted. Here
is my config:
<searchComponent name="spellcheck"
class="org.apache.solr.handler.component.SpellCheckComponent">
<lst name="defaults">
<!-- omp = Only More Popular -->
<str name="spellcheck.onlyMorePopular">false</str>
<!-- exr = Extended Results -->
<str name="spellcheck.extendedResults">false</str>
<!-- The number of suggestions to return -->
<str name="spellcheck.count">1</str>
</lst>
<str name="queryAnalyzerFieldType">spell</str>
<lst name="spellchecker">
<str name="name">default</str>
<str name="field">dictionary</str>
<str
name="classname">org.apache.solr.spelling.IndexBasedSpellChecker</str>
<str name="spellcheckIndexDir">spellchecker</str>
</lst>
<lst name="spellchecker">
<str
name="classname">org.apache.solr.spelling.FileBasedSpellChecker</str>
<str name="name">external</str>
<str name="sourceLocation">spellings.txt</str>
<str name="characterEncoding">UTF-8</str>
<str name="spellcheckIndexDir">spellchecker2</str>
</lst>
</searchComponent>
<queryConverter name="queryConverter"
class="org.apache.solr.spelling.SpellingQueryConverter"/>
<requestHandler name="/spellCheckCompRH"
class="org.apache.solr.handler.component.SearchHandler">
<arr name="last-components">
<str>spellcheck</str>
</arr>
</requestHandler>
spellings.txt contains:
pizza
history
http://localhost/solr/spellCheckCompRH?spellcheck=true&q=pizzza&spellcheck.dictionary=default&spellcheck.build=true
gives me a suggestion of pizza, works wonderfully.
http://localhost/solr/spellCheckCompRH?spellcheck=true&q=pizzza&spellcheck.dictionary=external&spellcheck.build=true
gives me no suggestions. (Even with a more fleshed out dictionary
file, I haven't been able to get suggestions for any query I've tried
for the external dictionary.)
In both cases I can see the indexes getting rebuilt, and the size of
external index varies with the size of my spellings.txt, so I know
that the contents of spellings.txt is getting indexed (and peeking
into the segment files, I see the text entries). It is as if
everything is getting set up correctly but the actual index is coming
up empty at query time.
Any suggestions for what I might be doing wrong?
Thanks!
Ron
