Hi Guys, I use following command to start solr cloud according to solr cloud wiki.
yydzero:example bjcoe$ java -Dbootstrap_confdir=./solr/conf -Dcollection.configName=myconf -DzkRun -DnumShards=2 -jar start.jar yydzero:example2 bjcoe$ java -Djetty.port=7574 -DzkHost=localhost:9983 -jar start.jar Then I have created several cores using CoreAdmin API ( http://localhost:8983/solr/admin/cores?action=CREATE&name= <coreName>&collection=collection1), and clusterstate.json show following topology: collection1: -- shard1: -- collection1 -- CoreForCustomer1 -- CoreForCustomer3 -- CoreForCustomer5 -- shard2: -- collection1 -- CoreForCustomer2 -- CoreForCustomer4 1) Index: Using following command to index mem.xml file in exampledocs directory. yydzero:exampledocs bjcoe$ java -Durl= http://localhost:8983/solr/coreForCustomer3/update -jar post.jar mem.xml SimplePostTool: version 1.4 SimplePostTool: POSTing files to http://localhost:8983/solr/coreForCustomer3/update.. SimplePostTool: POSTing file mem.xml SimplePostTool: COMMITting Solr index changes. And now SolrAdmin UI shows that 'coreForCustomer1', 'coreForCustomer3', 'coreForCustomer5' has 3 documents (mem.xml has 3 documents) and other 2 core has 0 documents. *Question 1:* Is this expected behavior? How do I to index documents into a specific core? *Question 2*: If SolrCloud don't support this yet, how could I extend it to support this feature (index document to particular core), where should i start, the hashing algorithm? *Question 3*: Why the documents are also indexed into 'coreForCustomer1' and 'coreForCustomer5'? The default replica for documents are 1, right? Then I try to index some document to 'coreForCustomer2': $ java -Durl=http://localhost:8983/solr/coreForCustomer2/update -jar post.jar ipod_video.xml While 'coreForCustomer2' still have 0 documents and documents in ipod_video are indexed to core for customer 1/3/5. *Question 4*: Why this happens? 2) Search: I use " http://localhost:8983/solr/coreForCustomer2/select?q=*%3A*&wt=xml" to search against 'CoreForCustomer2', while it will return all documents in the whole collection even though this core has no documents at all. Then I use " http://localhost:8983/solr/coreForCustomer2/select?q=*%3A*&wt=xml&shards=localhost:8983/solr/coreForCustomer2", and it will return 0 documents. *Question 5*: So If want to search against a particular core, we need to use 'shards' parameter and use solrCore name as parameter value, right? Thanks very much in advance! Regards, Yandong
