Sitecore search hits are null - solr

Question

I am running the below code
IQueryable<customSearchResultItem> query = context.GetQueryable<customSearchResultItem>().Where(CombinPredicates);
var hits = query.GetResults().Hits;
Sitecore.Diagnostics.Log.Info("search query hits:" + hits.Count(), context.Index);
foreach (var item in hits)
{
string builder = string.Empty;
try
{
string docitemid = item.Document.ItemId.ToString();
Sitecore.Diagnostics.Log.Info("document itemid:" + docitemid, item);
Item resultItem = item.Document.GetItem();
}
catch (Exception ex)
{
Sitecore.Diagnostics.Log.Info("search error going through hits:" + ex.Message, ex);
builder += item.Document.ItemId.ToString() + "\n";
continue;
}
}
the above actually returns results in the "hits" variable. However, I was getting zero results rendered out to the front end of the site. the code above is my debugging code to see what is going on.
With the hits I get back, I just loop through, nothing more.
When performing the loop and writing to logs, the below 2 lines actually return as expected, a valid Sitecore itemID
string docitemid = item.Document.ItemId.ToString();
Sitecore.Diagnostics.Log.Info("document itemid:" + docitemid, item);
However, the following line
Item resultItem = item.Document.GetItem();
returns as NULL
why would this be?
to complicate further, this code actual works in a one environment but not another, hence the reason for the debugging.
Also, the Sitecore item is present it both master and web databases and in the SOLR index

Answer 1

I've been having a similar problem where I was searching in the Prod (web) environment items indexed via the Stage Sitecore instance. I believe the GetItem() method uses the database, item id, language and version of the search result item, which are parsed from the _uniqueid that looks something like this:
...
"_uniqueid":"sitecore://stage/{d31b5802-c123-4690-86ff-8566dc896814}?lang=en&ver=1&ndx=my_site_index"
...
So in my case it wasn't finding the Sitecore item, because it was looking in the stage database, where as my Sitecore.Context.Database was the web one.
I know this answer is way late :-), but I hope it helps someone else who happens to run into this issue.
