I'm trying to search the examine index that was included with Umbraco Forms. I can see that the index is healthy and working when I try it from the backend, but it will not return results from my custom search result page on the front end.

This works for returning external pages:

        if (!String.IsNullOrEmpty(searchTerm) && ExamineManager.Instance.TryGetIndex("ExternalIndex", out IIndex index))
    {
        var searcher = index.GetSearcher();

        var criteria = searcher.CreateQuery("content", BooleanOperation.And)
        .GroupedOr(new List<string> { "combinedField" }, searchTerm);

        var searchList = criteria.Execute();
        var result = searchList.ToPublishedSearchResults(UmbracoContext.PublishedSnapshot.Content);

But if I simply replace the IndexName, IndexType and Field with the Umbraco Form Index values, nothing will return:

if (!String.IsNullOrEmpty(searchTerm) && ExamineManager.Instance.TryGetIndex("UmbracoFormsRecordsIndex", out IIndex index))
    {
        var searcher = index.GetSearcher();

        var criteria = searcher.CreateQuery("UmbracoForms", BooleanOperation.And)
        .GroupedOr(new List<string> { "RecordFields" }, searchTerm);

        var searchList = criteria.Execute();
        var result = searchList.ToPublishedSearchResults(UmbracoContext.PublishedSnapshot.Content);

Am I missing something obvious?

Thanks! md
