PDF Reader app - Search

I'm relatively new in the Power Apps world.

 

I'm building an app based on the PDF Reader template which allows a person to search within the PDF files.  For some reason, when I replaced the sample files with my own, the search function stopped working.

The formula there is: Default = " "

Should I be replacing it with my own formula?

How does it search text within the PDFs?

Hi @CarolynDC1 ,

 

Using the PDF viewer control you can indeed search within the files, but only within the context of the control. This does not apply to filtering the gallery.

 

Looking at the PDFGallery.Items property in the template, this filters two columns (PDFAuthor and PDFName) which are not necessarily linked to the PDF contents. 

 

Assuming you are using a library, to make this work, you'd have to add a column to the library and copy the text contents of the PDF in there so you can consume it in Power Apps...

Hi @CarolynDC1 ,

 

Do your PDFs contain text or images of text?

My PDFs are Power Point slides saved as PDFs.  There's text and links within them.

So I've come up with:

Items = If(SearchText.Text="", table name, Filter(table name, SearchText.Text in ...))

I'm not sure what to put in the ... in order for it to search the text within the PDF rather than the table the PDFs are linked to

Hi @CarolynDC1 ,

 

When you wrote PDF Reader template, I figured you meant the PDF viewer control, but I now think you meant something else. Can you please share a link to what you are using?

Sorry, I'm able to share the app as it's my company's policy.  But I have added a screen shot with the names of the PDFs blocked out so you can see what I'm working with in the attachment

HI @CarolynDC1 ,

 

No need to share the app and good you are security aware. The screenshot is already quite helpful since I now understand your question. So you wish to filter a gallery, based on the contents of the PDF files.

 

Unfortunately what you want is not possible since there is no object to reference the return of the FindText property.

I understand the template is experimental, but it does say "search within the files" in the description... I was just hoping someone knew how that would be possible. 🙁
