A query is a list of tokens separated by spaces. There is no quoting: a phrase with a space is two tokens. Each token is one of three things.

​
Free text

Every free-text token must match at least one of three fields: the hostname (as a substring, so vercel matches myapp.vercel.app), the page title, or the page text. Two tokens must both match, though not necessarily in the same field. Results are ranked by relevance. A match in the hostname counts more than a match in the title, which counts more than a match in the text.

​
Combining filters

  • Different keys are AND-ed. provider:vercel status:200 returns Vercel apps that answered 200.
  • Comma-separated values are OR-ed, except for domain:. status:200,301 returns apps that answered 200 or 301.
  • Free text is AND-ed with filters. netflix provider:vercel returns Vercel apps that mention netflix.
  • Repeating a key merges its values. provider:vercel provider:netlify is the same as provider:vercel,netlify.
  • Domains always AND. domain:acme.com,acme.io, like acme.com acme.io, returns apps tied to both. See Domain search.

​
Ordering without free text

A query made only of filters has nothing to rank by. Its results are ordered by hostname, or by most recently seen first when the query has a seen: filter. The exception is email: with a domain value, which runs as a text search and returns its results in no particular order.

​
What never appears

Only apps with a completed snapshot are searchable, so a hostname that has been discovered but not yet visited is invisible until its first snapshot. Hosts that stop resolving, or that their provider reports as no longer deployed, are marked dead and drop out of every search.
