Exact identifiers, matched exactly
Engineering documents live and die by exact strings. A part number, a register address, a spec clause number, an error code — these are identifiers where a partial match is a wrong answer. Searching a datasheet with a viewer’s find box that ignores case and matches substrings is actively risky when PN-1042 and PN-10425 are different components.
PDFSearch offers case-sensitive, whole-word matching precisely for this. Turn it on and an identifier matches exactly, across a whole stack of datasheets, specs, and standards loaded together — results grouped by document with page numbers so you can cite the spec and page. For the exact-match mechanics on their own, search text in PDF covers case-sensitive and whole-word modes in detail.
Proprietary specifications and internal design docs are parsed in your browser and never uploaded, so confidential material stays in-house. When your searchable set includes product manuals as well, searching technical manuals covers error-code and procedure lookups.
How it works
- 01
Load the datasheets and specs
Drag your datasheets, standards, and design docs onto the upload zone — up to 200 files, each up to 50 MB.
- 02
Search the identifier
Type the part number, register, or clause. Turn on case-sensitive and whole-word modes so the identifier matches exactly.
- 03
Locate it precisely
Results group by document with page numbers and the surrounding line, so you land on the exact spec reference.
- 04
Export references
Download matches to CSV — document, page, excerpt — for a design review or bill-of-materials cross-check.
Frequently asked questions
Can I match an exact part number?+
Yes. With case-sensitive and whole-word search enabled, a part number like PN-1042 matches only that string and not longer or differently-cased variants.
Can I search across many datasheets at once?+
Yes. Load up to 200 datasheets, specs, and standards together and run a single query across all of them, with results grouped by document.
Is case-sensitive search supported?+
Yes. Case sensitivity is a toggle, which matters for identifiers and register names where casing is significant.
Are proprietary specs kept confidential?+
Yes. All parsing happens in your browser; documents are never uploaded, so internal specifications and design files stay on your device.
Can I search a scanned standard?+
Only if it has an OCR text layer. Older scanned standards may be image-only — load one and search for a visible word to check before relying on it.
