Not able to get results in Solr - solr

Question

I do a full-import and I get the following response for the below command
http://localhost:8983/solr/karan/dataimport?command=full-import&commit=true&clean=false
But when I run the following snippet
public class SolrJSearcher {
public static void main(String[] args) throws SolrServerException, IOException {
SolrClient solr = new HttpSolrClient("http://localhost:8983/solr/karan");
SolrQuery query = new SolrQuery();
query.set("q", "karan");
QueryResponse response = solr.query(query);
SolrDocumentList results = response.getResults();
for (int i = 0; i < results.size(); ++i) {
System.out.println(results.get(i));
}
}
}
I get no results even though two rows are there.If I change the q to : I get two results without the name karan.Can you please clarify what is going wrong in this If I try in the sample project techproducts with the same changes I get the results as expected.
Solrconfig.xml
<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">
<lst name="defaults">
<str name="config">data-config.xml</str>
</lst>
</requestHandler>
data-config.xml
<dataConfig>

user="root"
password="kalkoti"/>
<document>
<entity name="id"
query="select id,name from testing">
</entity>
</document>
</dataConfig>
I have created the collection karan using
solr create -c karan

You aren't specifying what fields should be written to in your data-config.xml file. See https://cwiki.apache.org/confluence/display/solr/Uploading+Structured+Data+Store+Data+with+the+Data+Import+Handler
You haven't given us your full schema.xml or solrconfig.xml files, so it is hard to tell you exactly what to do, but Solr uses the select request handler as default, which uses the text field as the default search field. Meaning you will need to map whatever database column contains the term karan to the text field.
