Java usage example:

 SolrServer server = getSolrServer();
  SolrQuery solrQuery = new  SolrQuery().
                setQuery("ipod").
                setFacet(true).
                setFacetMinCount(1).
                setFacetLimit(8).
                addFacetField("category").
                addFacetField("inStock");
  QueryResponse rsp = server.query(solrQuery);
  
   SolrDocumentList docs = rsp.getResults();



Methods to implement:
======================
1).  SolrDocumentList search(SolrQuery query)

2).  SolrDocumentList search(String query, Integer start, Integer count, String[] fieldList) 
  
  query e.g. "*:*", "repl_verified: date range"
  
  fieldList e.g. "id,beginDate,endDate,title"
            e.g. "*"


3).     getSearchFields();
LukeResponse = LukeRequest.process(SolrServer server) 
  

Name = name of field
Type = type of field
Unique = number of unique terms, "distinct" element in Luke response
Records = number of documents that this field appear in (to be verified)


convenience methods:

4). SolrDocument getSolrDocument(String pid)

5). SolrDocumentList getDocumentsModifed(Date timestamp, boolean before, String field)
//before = true > return documents older than timestamp
//if field is null, the use datemodified

Python implementation:

             start=0, count=100):


  def getSearchFields(self):

returns a list of ('Name','Type','Unique','Records')
