LINQ concatenate 2 fields to search on - asp.net-mvc

Question

I'm trying to concatenate two fields in LINQ so that I can then filter with a keyword. I found a question posted here that I thought was my answer, but I'm getting 0 records back for some reason. This is supposed to return a JSON result for an autocomplete textbox (it works when I don't concatenate fields).
Here's my code:
Function CostCodeList(ByVal term As String) As ActionResult
Dim results = From c In db.ORG_CHART_V
Let Fullname = CStr(c.COSTCTR_CD & " - " & c.BREADCRUMB)
Where Fullname.ToUpper.Contains(CStr(term).ToUpper)
Order By Fullname
Select New With {.label = Fullname, .id = c.ORG_NODE_ID}
Return Json(results.ToArray, JsonRequestBehavior.AllowGet)
End Function
I'm also getting this error on the Return:
Public member 'ToArray' on type 'DbQuery(Of VB$AnonymousType_3(Of
String,Integer))' not found.
Before trying to concatenate the two fields I was searching on them separately, successfully. But when I concatenate them, it seems like everything I try either gets me an error and/or zero records.
Here is a different function that does work:
Function RoleList(ByVal term As String) As ActionResult
Dim list As New ArrayList
Dim results As IQueryable(Of JOB_ROLE)
If IsNumeric(term) Then
results = From c In db.JOB_ROLE
Where CStr(c.JBROLE_NO).StartsWith(term)
Else
results = From c In db.JOB_ROLE
Where c.JOB_ROLE_NAME.ToUpper.Contains(CStr(term).ToUpper)
End If
results = results.OrderBy(Function(e) e.JOB_ROLE_NAME)
For Each item In results
list.Add(New With {.label = item.JOB_ROLE_NAME, .id = item.JOB_ROLE_ID})
Next
Return Json(list.ToArray, JsonRequestBehavior.AllowGet)
End Function

Here is the new function that works as intended:
Function CostCodeList(ByVal term As String) As ActionResult
Dim list As New ArrayList
Dim results = db.ORG_CHART_V.Where(Function(e) (CStr(e.COSTCTR_CD) + " - " + e.BREADCRUMB).Contains(CStr(term).ToUpper)).OrderBy(Function(o) o.COSTCTR_CD)
For Each item In results
list.Add(New With {.label = item.COSTCTR_CD & " - " & item.BREADCRUMB, .id = item.ORG_NODE_ID})
Next
Return Json(list.ToArray, JsonRequestBehavior.AllowGet)
End Function
