SearchText / SearchNext for large document

I have a 320+ page PDF document.  When I search for a word that occurs frequently in the document, then all works well.  For one example, I have a word that occurs at the beginning of the document and then not again until page 299.  When I select to SearchNext after the the first occurrence, the search never seems to complete.  The app seems to be calling pdfviewer/RenderPdfPages for each page it is searching even though it will not be rendering those pages.  Perhaps it is just too slow and I do not wait long enough.  In any case, there is no feedback to the user.  Is there a way to get feedback as the search is being performed?  Perhaps some page number that is being searched of similar?

This is for Blazor Web Assembly client side.

Regards,
Arthur

Hi Arthur ,   
  
Thank you for Contacting Syncfusion support.

Thanks for the quick response.  There are two issues here:

1. The search never completes.  It seems to search on 10 or so pages and then quits.  Could this be due to some timeout?

2. There is no feedback to the user when the search takes a long time.

Regards,
Arthur

I am not seeing this in the latest v19.1.  Nor did I see anything in the documentation.  What do I need to do to turn this feature on?

Note that I am using a custom Find dialog and calling SearchText, SearchNext, and SearchPrevious.

Arthur

Thanks for the example:

I am using a custom Find dialog and calling SearchText, SearchNext, and SearchPrevious functions myself.  Is there any event that will give me feedback as to when the search is completed or when we reach the end of the document?  I am thinking there should be.  I want the search to wrap to the beginning when it gets to the end of the document.  Note that I use SfPdfViewer (WASM)

I also see this other issue when testing your example:
1. Search for "asdf"

Good Result => "Viewer has finished searching the document..."

2. Clear the search box and search for "abcde".  The document is still on page 1.

Bad Result => busy cursor just keeps on spinning

Arthur
