I'm trying to setup SOLR Cloud to work with my Sitecore 9.0 (Update-1) instance. I'm using 3 different VMs with [1-Zookeeper + 1-SOLR 6.6.2] configured on all machines. I have added the following collection to the SOLR.

enter image description here

The following code snippet, I used in a sublayout to print all items with templatename “Person”.

var index = Sitecore.ContentSearch.ContentSearchManager.GetIndex("sitecore_web_index");
using (var context = index.CreateSearchContext())
{
    var results = context.GetQueryable<Sitecore.ContentSearch.SearchTypes.SearchResultItem>()
        .Where(i => i.TemplateName == "Person");
            Response.Write("<h3>Search Results</h3><br />");
    Response.Write("<b>Total Item Count :: </b>" + results.Count());
    foreach (SearchResultItem searchResultItem in results)
    {

        Response.Write(searchResultItem.Path + "<br />");
    }
}

When I'm trying to print search result for the above code snippet, getting the following error :-

I am using Azure loadbalancer to connect to SOLR CLOUD. I'm able to successfully query on SOLR dashboard. But when I do a search query from my CD or CM envirnment,

Response.Write("<b>Total Item Count :: </b>" + results.Count());

It prints the total result count. But when the control enters the foreach loop, it throws the error.

foreach (SearchResultItem searchResultItem in results)

I believe the issue might be with SOLR Cloud configuration on distributed environment. How do I figure out what is wrong here? Thanks !

    Where is ContentSearch.Solr.ServiceBaseAddress pointing to? Is it pointing to loadbalancer? If yes, can you browse to loadbalancer url and query the same way as in Solr dashboard?

  • Do you have a value for the setting ContentSearch.SearchMaxResults in your Sitecore config? I've had a problem very similar to this and it turned out that SearchMaxResults is int.Max unless defined in your config. Sending the int.Max (2^31-1) value in queries to Solr gives all kinds of strange errors. If not set, set SearchMaxResults to something like 1000 or so.
