If you need to find a phrase in one Apple Notes folder on a Mac, the key limitation is that Notes’ documented search scope is an account or a single open note—not a selected folder. You can search the account that contains the folder, then use each result’s folder label to identify matches in your target folder. For a truly folder-only result list, Apple’s documented controls do not provide a direct filter; the practical workaround is to search the folder’s notes one at a time.
Search the account that contains the folder
Open Notes and make sure the folder sidebar is visible. If it is hidden, choose View > Show Folders. Find the folder under its account. Selecting a folder displays its notes in the notes area. Apple’s guide to viewing notes on Mac
Click the folder you want to search. Then click the Search button to show the search field. Click the arrow next to the magnifying glass and choose Current Account. Apple describes this as searching the account containing the selected folder; it does not describe this choice as limiting results to that folder. If you have multiple accounts, choose the one that contains the folder. All Accounts would broaden the search across accounts. Apple’s guide to searching notes on Mac
Enter a distinctive word or phrase and press Return. Start with a term likely to appear in the note itself, such as a project name or an uncommon phrase. Notes can search note bodies and, in supported cases, attachment filenames, PDFs, drawings, handwriting, text in scanned documents, and image contents. The search field also accepts natural-language phrases, such as “modified today,” according to Apple. Search capabilities can vary with accounts from other providers. Apple’s search documentation
Check the folder name shown with each result. Apple says matching notes appear with their folder locations, and that Top Hits can appear first based partly on title matches and how recently a note was updated. Open only results whose location is your target folder. Treat this as an account-wide search followed by a folder check; the folder label is what lets you discard matches from elsewhere.
Example
Suppose the folder is named “Renovation” and belongs to iCloud. Select it, set the search scope to Current Account, and search for “paint samples.” Review the folder location for each match. Keep results labeled “Renovation”; other results are valid account matches, but they are outside the folder you are trying to inspect. If another account also contains a folder called “Renovation,” this method searches only the chosen account, not folders with the same name in other accounts.
When you need to keep the search inside one folder
If account-wide results are too broad, search each note in the folder individually. First select the folder and open one of its notes. Press Command-F, enter the phrase in the search field that appears, and check that note. Repeat for the remaining notes in the folder. Apple documents Command-F as searching within a specific note, rather than as a folder-wide search. Apple’s guide to searching notes on Mac
This takes more steps, but the scope is clear: each search applies to the open note. It works best when the folder contains a manageable number of notes or when you know which notes are plausible candidates. For a large folder, use the account search first to narrow the candidates, then open only matching notes that belong to the target folder.
What Apple Notes does and does not offer
Apple’s search instructions describe scope controls for Current Account and All Accounts, suggested searches such as Shared Notes or Notes with Attachments, and searching within one note. They do not document a control for “this folder only.” So selecting a folder before typing is not enough evidence that search results are confined to that folder: follow the result locations and verify them. Apple’s search documentation
Smart Folders are not a direct substitute for searching one existing folder. They collect references to notes that meet criteria such as tags, mentions, checklists, or dates, and Apple says they do not contain the notes themselves. A Smart Folder can help maintain a recurring, criteria-based view, but it is not documented as a text-search filter for one ordinary folder. Converting an existing folder to a Smart Folder moves its notes to the Notes folder and tags them with the former folder name; Apple says that conversion cannot be undone. Do not convert a folder just to try to get a folder-scoped search. Apple’s Smart Folders guide
If the phrase does not appear in the results
Try a shorter or more distinctive term from the note, and confirm that the search is set to the account where the folder lives. If you are looking for text in a PDF, scan, image, handwriting, or drawing, remember that Apple lists these among searchable content, but the feature availability caveat for third-party accounts still applies. Open a likely note and use Command-F when you need to check its contents directly. A locked note may show only its title in results, even if it is unlocked, and Recently Deleted notes are included in search results; account for both when interpreting a match or an apparent omission. Apple’s search documentation
A quick decision guide
A few likely matches: Search the folder’s account, then confirm the folder label on every result.
A strict one-folder check: Open each note in that folder and use Command-F within the note.
A recurring criteria-based collection: Consider a Smart Folder only if its supported criteria fit your task; it does not turn ordinary text search into a folder-only filter.
Wallo can help organize open Mac windows and to-dos around a goal, with keyboard focusing, if keeping Notes and related work in view is part of your workflow. It does not change Apple Notes’ search scope. For the search itself, use the account search and verify folder locations, or check each note individually when folder-only scope matters.
