Latest information that I've found for this is that the error only occurs for shard2.
If I do a search for just shard1, those records that are assigned to shard1 will be able to be displayed. Only when I search for shard2 will the NullPointerException error occurs. Previously I was doing a search for both shards. Is there any settings that I required to do for shard2 in order to solve this issue? Currently I have not made any changes to the shards since I created it using http://localhost:8983/solr/admin/collections?action=CREATE&name=nps1&numShards=2&collection.configName=collection1 Regards, Edwin On 31 March 2015 at 09:42, Zheng Lin Edwin Yeo <edwinye...@gmail.com> wrote: > Hi Erick, > > I've changed the uniqueKey from id to Item No. > > <uniqueKey>Item No</uniqueKey> > > > Below are my definitions for both the id and Item No. > > <field name="id" type="string" indexed="true" stored="true" > required="false" multiValued="false" /> > <field name="Item No" type="text_general" indexed="true" stored="true"/> > > Regards, > Edwin > > > On 30 March 2015 at 23:05, Erick Erickson <erickerick...@gmail.com> wrote: > >> Well, let's see the definition of your ID field, 'cause I'm puzzled. >> >> It's definitely A Bad Thing to have it be any kind of tokenized field >> though, but that's a shot in the dark. >> >> Best, >> Erick >> >> On Mon, Mar 30, 2015 at 2:17 AM, Zheng Lin Edwin Yeo >> <edwinye...@gmail.com> wrote: >> > Hi Mostafa, >> > >> > Yes, I've defined all the fields in schema.xml.
