Hi All,

I know it's an old version and there are issues with umbraco being this old.. but we patched alot of stuff in the build a while back when we first developed the site.

We're running UmbracoExamine 0.9.1.0

We're getting a Null Reference on:

System.NullReferenceException: Object reference not set to an instance of an object.
   at UmbracoExamine.SearchResults.CreateSearchResult(Document doc, Single score) in C:\tomdev\umbracoexamine\UmbracoExamine\SearchResults.cs:line 32
   at UmbracoExamine.SearchResults.d__3.MoveNext() in C:\tomdev\umbracoexamine\UmbracoExamine\SearchResults.cs:line 59

   at System.Linq.Enumerable.WhereSelectEnumerableIterator`2.MoveNext()
   at System.Linq.Enumerable.WhereEnumerableIterator`1.MoveNext()

It's blowing up on this line

var results = ExamineManager.Instance.Search(QueryParser.Escape(searchTermFromUrl.ToLowerInvariant()), 100, false)
                    .Distinct()
                    .OrderByDescending(r => r.Score)
                    .Take(100)
                    .Select(r => new Node(r.Id))
                    .Where(n =>
                    {
                        bool visible = (n.Id != 0 && n.template != 0);
                        if (visible)
                        {
                            var nodeHidden = n.GetProperty("umbracoNaviHide");
                            if (nodeHidden != null && nodeHidden.Value == "1")
                            {
                                visible = false;
                            }
                        }
                        return visible;
                    });

and as the stacktrace shows in the examine source (from reflector alas I don't have the source):

private SearchResult CreateSearchResult(Document doc, float score)
{
    SearchResult <>g__initLocal0 = new SearchResult();
    <>g__initLocal0.Id = int.Parse(doc.GetField("id").StringValue());
    <>g__initLocal0.Score = score;
    SearchResult sr = <>g__initLocal0;
    IList fields = doc.GetFields();
    if (CS$<>9__CachedAnonymousMethodDelegate2 == null)
    {
        CS$<>9__CachedAnonymousMethodDelegate2 = new Func(null, (IntPtr) b__1);
    }
    foreach (Field field in Enumerable.Where(fields.Cast(), CS$<>9__CachedAnonymousMethodDelegate2))
    {
        sr.Fields.Add(field.Name(), field.StringValue());
    }
    return sr;
}

I'm thinking doc.GetField("id") might be returning null..

I've run the index through luke and at present can't seem to find anything glaringly obvious.. just wondering how i could get the examine source OR if anyone happened to have the same issues with the index occasionally blowing up..

I know i could just set it to reindex and it'd fix the search term BUT im wanting to know why as it keeps happening periodically.

Cheers, Tom
