How to Perform a Case-Sensitive Search in Acrobat on iPad

Product: Adobe Acrobat
Device & OS: iPad
Scenario: Searching for specific uppercase or lowercase text (e.g., finding the uppercase abbreviation "SS" without returning lowercase "ss") within a PDF document on an iPad.
Observed behavior: The search function in Acrobat for iPad ignores case sensitivity entirely, returning both uppercase and lowercase matches for the searched term.

Before you start

Verify that your Adobe Acrobat app is updated to the latest version in the App Store, as app features and search functionalities are periodically updated by the developer.

Solution 1Recommended

Use Adobe Acrobat on a Desktop Computer

Since the iPad version of Adobe Acrobat lacks the 'Match Case' feature, using the desktop application is the most direct way to perform a case-sensitive search on your PDF.

Mobile applications are often streamlined for touch interfaces and performance, which means advanced features like case-sensitive searching are sometimes omitted. The desktop version of Adobe Acrobat provides full advanced search capabilities.

Transfer the PDF to your computer

Save the PDF document to a cloud storage service like iCloud, Google Drive, or Dropbox from your iPad, then access it on your Windows or Mac computer.

Open the advanced search tool

Open the PDF in Adobe Acrobat Reader or Acrobat Pro. Press 'Shift + Ctrl + F' (Windows) or 'Shift + Cmd + F' (Mac) to open the Advanced Search window.

Enable case sensitivity

In the search window, check the box labeled 'Case-Sensitive' before typing your search query.

Execute the search

Type your exact uppercase or lowercase term (e.g., 'SS') and click 'Search' to find matches that strictly follow your capitalization.

Solution 2

Convert the PDF to a Word Document

By exporting the PDF to a Word document, you can use the advanced search tools available in mobile word processors to find case-sensitive matches.

Frequently Asked Questions

Why does my iPad PDF search return lowercase matches when I type uppercase letters?

Mobile applications like Adobe Acrobat for iPad use a simplified search engine designed for speed and ease of use on touch devices. This default search is case-insensitive, meaning it treats uppercase and lowercase letters as identical.

Can I use the 'Match Case' feature in Acrobat Reader for iPhone?

No. Similar to the iPad application, the Adobe Acrobat Reader app for iPhone currently lacks advanced search filters, including the 'Match Case' feature.

Is there a way to search for 'whole words only' in Acrobat on iPad?

Currently, Adobe Acrobat for iPad does not support a 'whole words only' filter. It performs a basic string search, which will highlight your search term even if it is embedded inside a longer word.

Will converting my PDF to Word allow me to do a case-sensitive search on my iPad?

Yes. Once you convert your PDF to a Word document (.docx), you can open it in a fully-featured word processor app. Many mobile word processors include an advanced 'Find and Replace' tool that supports case-sensitive searching.
