Question details
The user wants to find a way to search for specific keywords across multiple PDF files simultaneously on an iPad.

- Product
- Adobe Acrobat Reader Mobile App
- Device & OS
- iPad Pro
- Scenario
- Trying to quickly locate specific terms or information across a large collection of PDF documents on a mobile device.
- Observed behavior
- The advanced keyword search feature across multiple PDFs is not supported in the mobile app version.
Ensure your Adobe Acrobat Reader app is updated to the latest version. Because mobile apps have functionality limits, you will need access to a desktop computer for advanced multi-file searches.
Alternative Desktop Method and Feature Request
Since mobile apps currently lack this feature, using the desktop version of a PDF reader or requesting the feature from the developers are the best steps.
Currently, advanced keyword searching across multiple PDF files is not available in the Adobe Acrobat Reader mobile app. The mobile version is optimized for viewing and provides a more limited feature set compared to the desktop version.
To search across a collection of PDFs, you will need to transfer your files to a desktop application or submit a feature request to the developers for future iOS updates.
Use a cloud storage service like iCloud, Google Drive, or Dropbox to sync your PDF collection from your iPad Pro to a Mac or Windows PC.
Open a robust desktop PDF reader on your computer, press Shift+Cmd+F (Mac) or Shift+Ctrl+F (Windows) to open the Advanced Search tool, and select 'All PDF Documents in' to search your designated folder.
Go to the Adobe Feature Request and Bug Report Form online and submit a request to add multi-PDF search capabilities to the iPad application.

Frequently Asked Questions
Can I search for a specific word inside a single PDF on my iPad?
Yes, you can easily search within a single PDF. Open the document in your PDF reader app, tap the magnifying glass (search) icon usually located at the top of the screen, and type your keyword.
Is there any iOS native feature that can search text across multiple files?
The native iOS 'Files' app can sometimes perform basic text searches across indexed documents stored on your device, though it is generally not as thorough or detailed as dedicated advanced search tools on desktop software.
Why is advanced multi-PDF search not available on mobile apps?
Mobile applications are designed to be lightweight to conserve battery and memory. Searching through dozens or hundreds of PDFs simultaneously requires significant processing power and complex indexing capabilities typically reserved for desktop environments.
