Newbie Question
Hello
*I am trying to search for documents in my collection (Shakespeare). The
code is as follows:*
SolrClient client = new HttpSolrClient.Builder("
http://localhost:8983/solr/shakespeare").build();
SolrDocument doc = client.getById("2");
*However this does not return any document. What mistake am I making?*
Thank You
Deepak

I think you are missing /query handler endpoint in the URL. Plus actual
search parameters.
You may try using the admin UI to build your queries first.

*Hello*
*The code which worked for me:*
SolrClient client = new HttpSolrClient.Builder("
http://localhost:8983/solr/shakespeare").build();
SolrQuery query = new SolrQuery();
query.setRequestHandler("/select");
query.setQuery("text_entry:henry");
query.setFields("text_entry");
QueryResponse queryResponse = null;
try
{
queryResponse = client.query(query);
}
catch (Exception e)
{
}
System.out.println("Query Response: " +queryResponse.toString());
if (queryResponse!=null && queryResponse.getResponse().size()>0)
{
SolrDocumentList results = queryResponse.getResults();
for (int i = 0; i < results.size(); ++i) {
SolrDocument document = results.get(i);
System.out.println("The result is: " +results.get(i));
System.out.println("The Document field names are: "
+document.getFieldNames());
}
}
*The data:*
{"index":{"_index":"shakespeare","_id":0}}
{"type":"act","line_id":1,"play_name":"Henry IV",
"speech_number":"","line_number":"","speaker":"","text_entry":"ACT I"}
{"index":{"_index":"shakespeare","_id":1}}
{"type":"scene","line_id":2,"play_name":"Henry
IV","speech_number":"","line_number":"","speaker":"","text_entry":"SCENE I.
London. The palace."}

The getById method accesses the handler named "/get", normally defined
with the RealTimeGetHandler class. In recent Solr versions, the /get
handler is defined implicitly and does not have to be configured, but in
older versions (not sure which ones) you do need to have it in
solrconfig.xml.
I didn't expect your code to work because getById method returns a
SolrDocumentList and you have SolrDocument, but apparently this actually
does work. I have tried code very similar to yours against the
techproducts example in version 7.1, and it works perfectly. I will
share the exact code I tried and what results I got below.
What code have you tried after the code you've shared? How are you
determining that no document is returned? Are there any error messages
logged by the client code or Solr? If there are, can you share them?
Do you have a document in the shakespeare index that has the value "2"
in whatever field is the uniqueKey? Does the schema have a uniqueKey
defined?
Can you find the entry in solr.log that logs the query and share that
entire log entry?
Code:
public static void main(String[] args) throws SolrServerException,
IOException
{
String baseUrl = "http://localhost:8983/solr/techproducts";
SolrClient client = new HttpSolrClient.Builder(baseUrl).build();
SolrDocument doc = client.getById("SP2514N");
System.out.println(doc.getFieldValue("name"));
}
Console log from that code:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for
further details.
Samsung SpinPoint P120 SP2514N - hard drive - 250 GB - ATA-133
Including the collection/core name in the URL is an older way of writing
SolrJ code. It works well, but multiple collections can be accessed
through one client object if you change it and your SolrJ version is new
enough.
Thanks,
Shawn
