RE: Spell Checker

[Eric Martin]

Thanks Dan! Few questions:

Use a<copyField>  to divert your main text fields to the spell field and
then configure your spell checker to use the "spell" field to derive the
spelling index.
This will still keep my current copyfield for the same data, right?

I don't need to rebuild, just reindex.

" After this, you'll need to query a spellcheck-enabled handler with
spellcheck.build=true or enable spellchecker index builds during optimize."

Totally lost on that. 

I will buy a book here shortly.

I had to deal with spellchecking today a bit. Make sure you are 
performing the analysis step at index-time as such:

schema.xml:

    <fieldType name="textSpell" class="solr.TextField"
    positionIncrementGap="100" omitNorms="true">
    <analyzer type="index">
    <tokenizer class="solr.StandardTokenizerFactory"/>
    <filter class="solr.StopFilterFactory" ignoreCase="true"
    words="stopwords.txt"/>
    <filter class="solr.LowerCaseFilterFactory"/>
    <filter class="solr.StandardFilterFactory"/>
    </analyzer>
    <analyzer type="query">
    <tokenizer class="solr.StandardTokenizerFactory"/>
    <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt"
    ignoreCase="true" expand="true"/>
    <filter class="solr.StopFilterFactory" ignoreCase="true"
    words="stopwords.txt"/>
    <filter class="solr.LowerCaseFilterFactory"/>
    <filter class="solr.StandardFilterFactory"/>
    </analyzer>
    </fieldType>

<fields>
             .....
<field name="spell" type="textSpell" indexed="true" stored="false" 
multiValued="true"/>
</fields>

 From http://wiki.apache.org/solr/SpellCheckingAnalysis:

    Use a<copyField>  to divert your main text fields to the spell field and
then configure your spell checker to use the "spell" field to derive the
spelling index.


After this, you'll need to query a spellcheck-enabled handler with 
spellcheck.build=true or enable spellchecker index builds during optimize.

Hope this helps,
