+aliases: [payload-sort, payload-query-sort]
+tags: [payloadcms, queries, sort, api]
+sources: [raw/queries__sort.md]

+
+## Overview
+
+Documents can be sorted by any **top-level stored field**. Prefix with `-` for descending order; no prefix = ascending.
+
+> **Constraint:** Virtual fields cannot be used for sorting unless [[wiki/payloadcms/fields-relationship|linked with a relationship field]]. The field must exist in the database.
+
+> **Performance:** Enable `index: true` on fields you sort by. See [[wiki/payloadcms/database-indexes|Database Indexes]].
+
+---
+
+## Local API
+
+```ts
+// Single field — ascending
+const posts = await payload.find({
+  collection: 'posts',
+  sort: '-createdAt',           // descending
+})
+
+// Multiple fields
+const posts = await payload.find({
+  collection: 'posts',
+  sort: ['priority', '-createdAt'],  // array of strings
+})
+```
+
+---
+
+## REST API
+
+```
+GET /api/posts?sort=-createdAt
+GET /api/posts?sort=priority,-createdAt    // comma-separated
+```
+
+Using `qs-esm` query string builder (array form):
+
+```ts
+import { stringify } from 'qs-esm'
+
+const query = stringify({ sort: ['priority', '-createdAt'] }, { addQueryPrefix: true })
+fetch(`/api/posts${query}`)
+```
+
+---
+
+## GraphQL API
+
+```graphql
+# Single field
+query {
+  Posts(sort: "-createdAt") {
+    docs { color }
+  }
+}
+
+# Multiple fields — comma-separated string
+query {
+  Posts(sort: "priority,-createdAt") {
+    docs { color }
+  }
+}
+```
+
+---
+
+## Syntax Summary
+
+| Context | Multiple fields | Descending prefix |
+|---------|----------------|-------------------|
+| Local API | Array of strings | `-fieldName` |
+| REST API | Comma-separated string or array | `-fieldName` |
+| GraphQL | Comma-separated string | `-fieldName` |
+
+---
+
+## Key Takeaways
+
+- `-fieldName` = descending; `fieldName` = ascending — works across all three APIs
+- Local API accepts an **array**; REST/GraphQL accept a **comma-separated string** (REST also accepts array via qs)
+- Only **stored fields** are sortable — virtual fields require a relationship link to be sortable
+- Add `index: true` to sort fields for query performance; compound sorts benefit from compound indexes (see [[wiki/payloadcms/database-indexes|Database Indexes]])
+- Sort is complementary to [[wiki/payloadcms/queries-pagination|pagination]] and [[wiki/payloadcms/queries-select|select/populate]]
