+### `find` options: canonical and legacy
+
+The signature above accepts `QueryOptions | QueryOptionsV2`, and the Canonical source
+declares which of the two to write. `QueryOptionsV2` is *"canonical query options using
+Spec protocol field names … the recommended interface for `data.find()` queries"*, while
+`QueryOptions` carries an `@deprecated` tag in the same file describing *"legacy parameter
+names … that require translation to QueryAST"*, with the instruction to *"prefer QueryAST
+fields directly"*. Both interfaces are declared in `packages/client/src/index.ts`, so the
+recommendation is the SDK's own, not this page's.
+
+| Canonical (`QueryOptionsV2`) | Legacy (`QueryOptions`) | Clause |
+|:---|:---|:---|
+| `where` | `filter` | filter conditions (`WHERE`) |
+| `fields` | `select` | field selection (`SELECT`) |
+| `orderBy` | `sort` | sort definition (`ORDER BY`) |
+| `limit` | `top` | maximum records (`LIMIT`) |
+| `offset` | `skip` | records skipped (`OFFSET`) |
+
+**Write the left column.** Those are the QueryAST and protocol field names, so the same
+words carry from here down through `data.query()` into the query layer — one translation
+step fewer to hold in your head.
+
+**The right column still works.** Nothing refuses it: `find` recognises a canonical
+options object and normalizes it into exactly the transport parameters the legacy names
+produce, so the two columns are equivalent, not merely similar. Deprecated here means
+"prefer the other spelling", not "scheduled for removal in this version".
+
+**Use one column per call.** `find` reads either the canonical names or the legacy ones
+for a given options object, never a blend — a key from the other column is dropped
+silently rather than refused, so migrate an options object as a whole.
