How to find a PDF by what's in it

You remember that a PDF mentioned a 30-day notice period, or that it had a table comparing three suppliers on price. You don’t remember what the file was called, which folder it went into, or whether it arrived by email or download. The words in your head are a paraphrase of what the document said, and the filename is probably something like scan_0032.pdf.

This page covers the ways people usually track down a PDF from its contents, and how to find one in Fabric by describing what it said, including when your wording doesn’t match the document’s.

How people usually look for a PDF they can’t name

The first stop is often the computer’s own search. Spotlight on a Mac and Windows search both index text inside many PDFs, so a distinctive word from the document can bring it up. That works well when you remember an exact term. A paraphrase, such as “the clause about ending the lease early”, tends to return nothing useful or a long list of unrelated files.

Cloud drives such as Google Drive and Dropbox search inside documents as well, which helps if every PDF lives in that one account. In practice, PDFs end up split between the drive, the inbox and the downloads folder, and each of those is a separate search with its own habits.

The fallback is opening likely files one by one and pressing Ctrl+F inside each. Some people upload a few candidate PDFs to ChatGPT and ask which one mentions the topic. Both approaches work for a handful of files, and both depend on already knowing roughly which files to check.

Step 1: Put your PDFs where one search reaches them

Drag PDFs into Fabric, paste them, or click Upload a file, which handles large batches. If you prefer working from Finder or File Explorer, the Fabric desktop app mounts Fabric as a virtual drive on Mac, Windows and Linux, and files there stream when opened instead of taking up disk space.

PDFs that arrive as attachments can be forwarded to your Fabric email address, which accepts mail from your verified account address. PDFs already in Google Drive can come across through a connection with two-way sync. Connections need a paid plan.

As each PDF arrives, Fabric creates embeddings so search can match it by meaning, writes a short summary, extracts attributes such as content type and topics, and suggests tags. That automatic organization happens without you filing anything, so a PDF dropped into the root of your library is as findable as one in a neat folder.

Step 2: Describe what the PDF said

Click Search, or press Cmd+F (Mac) / Ctrl+F (Windows), and type what you remember in plain language. Fabric search is hybrid, matching by meaning and by keyword at once. A query like “notice period for ending the tenancy” can find a lease that says “termination requires two months’ written notice”, even though the two share few words.

Describe the subject, the purpose, or a detail that stuck. “Supplier quote with prices per thousand units”, “letter from the council about parking permits” and “study on sleep and memory in older adults” are all reasonable queries. When you open a result, it jumps to the page where the match appears, so you can confirm it’s the right file without scrolling through forty pages.

Scanned PDFs work the same way. Search covers text inside images, including photographed text, so a scanned letter from a bank is searchable by what it says. How to search your scanned documents goes into scanning in more detail.

Step 3: Narrow the results

If a description brings back too much, add a filter. You can limit results by kind of item (to show only PDFs), by tag, or by location in your file system, such as a Work or Household folder.

When part of the document is clear in your memory, put it in quotes. Quoted words are matched strictly, which suits reference numbers, policy numbers, people’s names and exact phrases. A described query and a quoted term can sit together, so “insurance renewal” plus a quoted policy number narrows quickly.

If you find a PDF that’s close but not the one you want, such as last year’s version of a report, select it and run similarity search. Fabric finds items like it across your library, which often surfaces the newer edition or a related document you’d forgotten about.

Step 4: Ask the AI assistant when you only have the gist

Sometimes the question is “which document said that?” rather than a search term. Ask the AI assistant something like “Which PDF mentioned the penalty for late delivery?” It runs an agentic search across Fabric and your connected apps and answers with clickable references to the source files, so you can open the PDF it drew from and check.

To keep the assistant focused, open a folder and start the assistant there, and it limits itself to that folder. You can also right-click a folder and add it to the assistant’s context without opening it. Follow-up questions work, so you can ask it to compare the PDF it found with another one, and save a useful answer as a note.

The knowledge search panel, on the right of the search screen on web and desktop or in the bottom drawer on mobile, does the same kind of search across Fabric and connected apps such as Gmail or Outlook. It helps when you aren’t sure whether the PDF was saved or only received.

Frequently asked questions

Can I find a PDF without remembering any exact words from it?

Yes. Fabric search matches by meaning as well as keywords, so a description in your own words can find a PDF that phrases things differently.

Does search work on scanned PDFs?

Yes. Search covers text inside PDFs and images, including photographed text, so scanned letters and forms are searchable by what they say.

How do I search for an exact phrase inside a PDF?

Put the phrase in quotes. Quoted words are matched strictly, which is useful for names, reference numbers and specific wording.

Can I limit search results to PDFs only?

Yes. Use the kind of item filter. You can also filter by tag or by location in your files.

Does the search result show where in the PDF the match is?

Yes. Opening a result takes you to the exact page where the match appears.

Can AI tell me which PDF contains a particular fact?

Yes. Ask the Fabric AI assistant, and it answers with clickable references to the PDFs it used, so you can check the source.

What if I can’t remember a file’s name or type at all?

Describe what it was about and let search do the matching. How to find a file when you don’t remember its name covers more approaches for any kind of file.

Do I need to organize my PDFs before I can search them?

No. Fabric summarizes and extracts attributes from each PDF as it arrives, and search reads the contents, so folders and tags are optional.

Can I search PDFs on the free plan?

File uploads are included on the free plan, and AI use is limited there. Connecting Google Drive or other apps needs a paid plan. See pricing for current plans.
