Hi,
Append &debugQuery=true to your request URLs to see what's going on.
Here is something I've used in the past. I suggest you throw out everything
but n-grams while you're debugging.
<!-- n-gram tokenization -->
<fieldType name="unigram" class="solr.TextField" positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="org.apache.solr.analysis.NGramTokenizerFactory"
minGramSize="1" maxGramSize="1"/>
</analyzer>
<analyzer type="query">
<tokenizer class="org.apache.solr.analysis.NGramTokenizerFactory"
minGramSize="1" maxGramSize="1"/>
</analyzer>
</fieldType>
...
...
<field name="text_cn" type="unigram" indexed="true" stored="true"
required="true"/>
