Purpose of SolrDocument.java

[stockii <st...@shopgate.com>]

I worling through the SolrCode and i want to know how the class SolrDocument
used in Solr !?

When i start and debug a normal search, SolrDocument never been used.
(Standard SearchHandler with q-Query). i thought, this class is a
representation of a Doc from the Index as a higher level doc above the
lucene doc. 

so i thougt that solr convert a lucene doc to a SolrDoc and work with this.
but solr doing an prefetch with DocSllice/DocSet/DocList ... an get the real
lucene doc in the XML-Writer for the response.

So for what is SolrDocument ????

SolrDocument is under org.apache.solr.common which is for the
solr-solj.jar and not available for the solr-core.jar
see e.g.:
http://lucene.apache.org/solr/api/org/apache/solr/common/SolrDocument.html
http://www.jarvana.com/jarvana/view/org/apache/solr/solr-solrj/1.4.1/solr-solrj-1.4.1.jar!/org/apache/solr/common/SolrDocument.class?classDetails=ok

So, yes. I think, it is only for solrj ('handle queries + responses in
pure Java')

Regards,
Peter.

Hi,

you can use it via SolrJ:

QueryResponse rsp = solrServer.query(query);
SolrDocumentList docs = rsp.getResults();

for (SolrDocument doc : docs) {
    long id = (Long) doc.getFieldValue("id");
     // create your higher level object here ...
}

SolrJ get the docs either from xml or binary stream (from a remote
connection to a solr server) depending on what you have set at
initialization time:
solrServer.setParser(new BinaryResponseParser());

Regards,
Peter.
