Save one file and open it in your browser. Download contains the application only, without your search terms or IDs. Running the search requires internet access and may require a Facebook login.

Experimental search helper. Facebook controls its search results and may ignore advanced filters or change its URL format. This tool does not bypass privacy settings, access restrictions or login requirements. An empty result does not establish that content or a relationship does not exist.
01 / BUILD YOUR QUERY

Start with a search

Searches are built on this device. Nothing is sent to Facebook while you type.

Advanced filters · experimental

These encodings come from the supplied prototype and have not been verified against live Facebook results. Unavailable filters are disabled and omitted from the link. Compare results with an unfiltered search.

Uses the prototype’s location filter; separate hometown and visited modes are not implemented.

Calendar dates use this device’s local date. Facebook determines how boundaries affect results.

Use only IDs you are authorized to handle. Facebook Matrix / ID guidance ↗ opens Plessas.net; no search fields are included in that link.

How to use

  1. Select a search type and enter keywords. Optional filters require appropriate numeric Facebook IDs.
  2. Review the included fields and generated URL. Disabled fields are excluded; their values remain available if you switch back.
  3. Copy the link, or approve sending it to Facebook and open the search. Facebook decides what your logged-in account can see.
  4. Verify results independently. Record source URLs, collection times and evidence references in your own investigation records.

No search history, local storage, cookies, trackers, AI calls or external libraries are used by this tool. Clearing or closing the page removes its in-memory query. Browser history, clipboard and Facebook may retain information after you use a link.
