Search an exact handle
Enter the username without extra profile text. The leading @ is optional. DeepSearch checks public profile patterns, open APIs, search results, and a broad catalog of public sites where that handle may appear.
If you care about particular networks, choose them in the platform picker so the search can prioritize those surfaces.
A reused handle is a clue, not proof
People often reuse distinctive usernames, so the same rare handle across several sites can be a strong signal. Common or short handles can also belong to different people on different networks.
DeepSearch keeps profiles separate when the surrounding evidence conflicts. You should do the same when the names, photos, languages, or locations do not fit.
