Hi there,

Do you have a link to a file that the search is not working on? How are you performing the search? it looks like you aren’t doing it programmatically, is that correct?

Best Regards,

Hi there,

Are you able to search this PDF using our demo site? PDF.js Viewer Demo | PDF.js Express

I was not able to reproduce this issue. On our demo site I was able to search this PDF for the term “coder”.

I also tried searching “coder” in Adobe Acrobat and I found 14 results as well.

Could you provide the code you are using to search?

Best Regards,
