SOLRJ - Searching text in all fields of a Bean
Hi,
I have two fields in the bean class, id and title.
After adding the bean to SOLR, I want to search for, say "kitten", in all
defined fields in the bean, like this -- query.setQuery( "kitten"); --
But I get results only when I affix the bean field name before the search
text like this -- query.setQuery( "title:kitten"); --
Same case even when I use SolrInputDocument, and add these fields.
Can we search text in all fields of a bean, without having to specify a
field?
If we can, what am I missing in my code?
*Code:*
Bean:
---
public class SOLRTitle {
@Field
public String id = "";
@Field
public String title = "";
}
---
Indexing function:
---
private static void uploadData() {
try {
... // Get Titles
List solrTitles = new
ArrayList();
Iterator it = titles.iterator();
while(it.hasNext()) {
Title title = (Title) it.next();
SOLRTitle solrTitle = new SOLRTitle();
solrTitle.id = title.getID().toString();
solrTitle.title = title.getTitle();
solrTitles.add(solrTitle);
}
server.addBeans(solrTitles);
server.commit();
} catch (SolrServerException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
---
Querying function:
---
private static void queryData() {
try {
SolrQuery query = new SolrQuery();
query.setQuery( "kitten");
QueryResponse rsp = server.query( query );
List beans = rsp.getBeans(SOLRTitle.class);
System.out.println(beans.size());
Iterator it = beans.iterator();
while(it.hasNext()) {
SOLRTitle solrTitle = (SOLRTitle)it.next();
System.out.println(solrTitle.id);
System.out.println(solrTitle.title);
}
} catch (SolrServerException e) {
e.printStackTrace();
}
}

Re: SOLRJ - Searching text in all fields of a Bean
Ahmet,
I got it working to an extent.
Now:
SolrQuery query = new SolrQuery();
query.setQueryType("dismax");
query.setQuery( "kitten");
query.setParam("qf", "title");
QueryResponse rsp = server.query( query );
List beans = rsp.getBeans(SOLRTitle.class);
System.out.println(beans.size());
Iterator it = beans.iterator();
while(it.hasNext()) {
SOLRTitle solrTitle = (SOLRTitle)it.next();
System.out.println(solrTitle.id);
System.out.println(solrTitle.title);
}
*This code is able to find the record, and prints the ID. But fails to print
the Title.*
Whereas:
SolrQuery query = new SolrQuery();
query.setQuery( "title:kitten" );
QueryResponse rsp = server.query( query );
SolrDocumentList docs = rsp.getResults();
Iterator iter = rsp.getResults().iterator();
while (iter.hasNext()) {
SolrDocument resultDoc = iter.next();
String title = (String) resultDoc.getFieldValue("
title");
String id = (String) resultDoc.getFieldValue("id"); //id is
the uniqueKey field
System.out.println(id);
System.out.println(title);
}
*
This query succeeds!*
What am I doing wrong in dismax params? The title field is being fetched as
Null.
Regards,
Subhash Bhushan.

Hi Savvas,
Thanks!! Was able to search using directive.
I was using the default example schema packaged with solr. I added the
following directive for title field and reindexed data:
