Find posts published in the last 30 days

MongoDB query compiled from plain English against the blog sample schema, then verified by running it.

The compiled query

{
  "type": "find",
  "collection": "posts",
  "filter": {
    "publishedAt": {}
  }
}

How the compiled query works

Filters posts on publishedAt.

Things worth knowing

:thirtyDaysAgo is resolved when the query runs, not when it is written — so the query keeps meaning "the last N days" instead of freezing to a fixed date.

Write this in plain English instead. Mask Databases compiles the sentence above into exactly this query at build time — no AI at runtime, and you can read the output in a diff.
