Hi, I've followed the docs and implemented PDFIndex and MultiSearcher.

In the backend these are both healthy and return results.

However, when I use them in code I get zero results from the PdfIndex either directly or via the MultiSearcher.

This is the code which creates the PdfIndex and MultiSearcher...

public void Initialize()
        {
            //Get both the external and pdf index
            if (_examineManager.TryGetIndex(Constants.UmbracoIndexes.ExternalIndexName, out var externalIndex)
                && _examineManager.TryGetIndex(PdfIndexConstants.PdfIndexName, out var pdfIndex))
            {
                //register a multi searcher for both of them
                var multiSearcher = new MultiIndexSearcher("MultiSearcher", new IIndex[] { externalIndex, pdfIndex });
                _examineManager.AddSearcher(multiSearcher);
            }
        }

This is how I'm searching the PdfIndex directly...

var textFields = new[]
            {
                "title", "description", "content", "bodyText", "location", "pageHeading", "subHeading",
                "nodeName", "__NodeTypeAlias"
            };

if (ExamineManager.Instance.TryGetIndex("PDFIndex", out index))
                {
                    searcher = index.GetSearcher(); ;

                    var query = searcher.CreateQuery("media").GroupedOr(textFields, searchQuery.Fuzzy(0.2f));
                    results = query.Execute();
                }

...and this is a search against the MultiSearcher

if (_searchPdf && ExamineManager.Instance.TryGetSearcher("MultiSearcher", out searcher))
                {
                    var query = searcher.CreateQuery("media,content").GroupedOr(textFields, searchQuery/*.Fuzzy(0.2f)*/);
                    results = query.Execute();
                }

I suspect I'm phrasing the search incorrectly. I'll continue to "fiddle" and strip the code down to minimum.

Suggestions appreciated.
