How to Search for Keywords on a Mac: 4 Methods

When you need to find a word on your Mac, the right method depends on where you are searching.

If the webpage or document is already open, use Command-F. If you need to find a file, use Spotlight or Finder. If the information could be buried across PDFs, images, presentations, audio, or video, you need a tool that searches inside all those files.

Quick answer

• Search the page or document currently open: press Command-F.

• Search a PDF in Preview: press Command-F, then use the results sidebar to move between matches.

• Search files across your Mac: press Command-Space and use Spotlight, or press Command-F in Finder for more filters.

• Search inside many files and formats at once: use Fenn to search by exact keyword or meaning and open the relevant page, slide, image, or timestamp.

1. Search the open webpage or document with Command-F

Command-F is the fastest option when you already have the correct webpage, PDF, note, spreadsheet, or document open.

1. Press Command-F.

2. Enter the word or phrase.

3. Press Return to move to the next result.

4. Use Shift-Return to move to the previous result in most apps.

This works in Safari, Chrome, Firefox, Pages, Microsoft Word, Google Docs, Notes, and most other Mac apps.

Use a distinctive part of the phrase if the document contains too many results. Searching for termination for convenience will usually be more useful than searching for termination alone.

Limitation: Command-F searches only the item currently open. It cannot tell you which file contains the phrase.

2. Search for words in a PDF on Mac

Preview can search any PDF that contains selectable text.

1. Open the PDF in Preview.

2. Press Command-F or use the search field in the toolbar.

3. Enter a word or phrase.

4. Select a result to jump to the matching page.

Preview treats a phrase as an exact phrase by default. You can open the search options and choose Any Match when you want results containing any of the words.

If Preview cannot find text in a scanned document, the PDF may contain images instead of selectable text. On supported macOS versions, Preview can recognize the text when you choose File > Export > Embed Text. For large collections of scanned documents, an OCR-aware search tool is more practical.

3. Search files with Spotlight or Finder

Use Spotlight when you do not know which file contains the keyword.

1. Press Command-Space.

2. Enter the keyword or phrase.

3. Select a result and press Return to open it.

4. Hold Command while selecting a file to see its location.

Narrow Spotlight results with operators

Spotlight supports filters that make broad searches more useful:

• kind:pdf invoice searches PDFs related to “invoice.”

• kind:image receipt searches images related to “receipt.”

• name:contract searches for files with “contract” in the name.

• author:John proposal searches for proposals associated with that author.

• title:budget searches for items with “budget” in the title.

Apple maintains a longer list in its Spotlight search guide.

Use Finder when you need more control

Finder uses the same underlying search index but gives you more visible filters.

1. Open Finder.

2. Press Command-F.

3. Choose This Mac or the current folder.

4. Enter your keyword.

5. Select the + button to filter by kind, name, date, or another attribute.

You can combine multiple criteria and save a useful search as a Smart Folder. Apple explains the available criteria in its Finder search guide.

For more examples, see the guide to Spotlight search operators.

4. Search across many files with Fenn

Spotlight and Finder are useful for locating likely files. The difficult part is often finding the exact information inside them.

You may remember:

• a clause inside one of hundreds of PDFs;

• a number inside a spreadsheet;

• text shown in a screenshot;

• a chart inside a presentation;

• something said during a recording;

• the subject of an image, without knowing its filename.

Fenn indexes supported content on your Mac and lets you search in four ways:

• Keyword search when you remember the exact words.

• Exact search when the wording must match precisely.

• Semantic search when you remember the idea but not the wording.

• Hybrid search when you want both keyword and meaning-based results.

The result includes enough context to confirm the match. Opening it takes you to the relevant PDF page, presentation slide, image, audio timestamp, or video frame instead of leaving you to search through the file manually.

Fenn runs on Apple Silicon and processes files on-device by default. This is useful when your search includes confidential contracts, financial documents, research, source material, or client files.

See Fenn pricing and download options.

You can also learn more about finding text in screenshots and images or compare semantic and keyword search.

Which Mac search method should you use?

• Use Command-F when the correct webpage or document is already open.

• Use Preview search when you have one searchable PDF open.

• Use Spotlight when you need a quick search across indexed Mac content.

• Use Finder when you need folder scope or detailed filters.

• Use Fenn when you need to search inside many files and open the exact matching page, slide, image, or timestamp.

Why a keyword search may return no results

If you know the information exists but cannot find it, check these common causes:

• The app is searching only the current document.

• Spotlight has not indexed the relevant folder or drive.

• The file is excluded from Spotlight settings.

• The PDF is a scan without recognized text.

• The text appears inside an image, audio recording, or video.

• You remember the meaning but not the exact words.

Changing the search method is usually more useful than repeating the same query.
