> ## Agent Instructions
> FalkorDB is a graph database that speaks the Redis protocol. Queries are issued as OpenCypher through the GRAPH.QUERY and GRAPH.RO_QUERY commands, not over Bolt or a SQL connection.
> FalkorDB implements a subset of OpenCypher with proprietary extensions. Do not assume Neo4j-only syntax or procedures are available — check /cypher/cypher-support and /cypher/known-limitations before using a clause.
> FalkorDB is the successor to RedisGraph, but they are separate products. Do not present RedisGraph commands, versions, or limitations as current FalkorDB behavior.
> Use the official clients listed in /getting-started/clients rather than generic Redis or Neo4j drivers, and prefer the language the user is already working in.
> Configuration parameters are set with GRAPH.CONFIG SET or at startup; cite the exact parameter name from /getting-started/configuration rather than inventing one.
> This site covers four products: FalkorDB (core), FalkorDB Cloud, FalkorDB Enterprise, and the GraphRAG SDK. Name which one an answer applies to, since setup and operations differ.

# Commands

> Reference for every FalkorDB command, from running openCypher queries with GRAPH.QUERY to managing configuration, constraints, indexes, and graph metadata.

## FalkorDB Features

FalkorDB is a graph database that exposes its functionality using the [openCypher](https://opencypher.org/) query language. Its basic commands accept openCypher queries, while additional commands are exposed for configuration or metadata retrieval.

## FalkorDB API

Command details can be retrieved by filtering for the [module](/commands/?group=graph) or for a specific command, e.g., `GRAPH.QUERY`.
The details include the syntax for the commands, where:

* Optional arguments are enclosed in square brackets, for example `[timeout]`.
* Additional optional arguments are indicated by an ellipsis: `...`

Most commands require a graph key name as their first argument.

## Frequently Asked Questions

<AccordionGroup>
  <Accordion title="What query language does FalkorDB use?">
    FalkorDB uses the **openCypher** query language, an open standard for graph query languages. Most of the Cypher specification is supported.
  </Accordion>

  <Accordion title="How are FalkorDB commands structured?">
    FalkorDB commands are Redis module commands prefixed with `GRAPH.` (e.g., `GRAPH.QUERY`, `GRAPH.DELETE`). Most commands require a graph key name as their first argument.
  </Accordion>

  <Accordion title="What does the square bracket notation mean in command syntax?">
    Square brackets like `[timeout]` indicate optional arguments. An ellipsis (`...`) after optional arguments means additional optional parameters may follow.
  </Accordion>

  <Accordion title="Do I need to create a graph before querying it?">
    No. FalkorDB automatically creates a graph when you first run a `GRAPH.QUERY` command against a new graph key name. There is no separate 'CREATE GRAPH' command.
  </Accordion>

  <Accordion title="Can I use FalkorDB with any Redis client?">
    Yes. Since FalkorDB is a Redis module, you can use any Redis client to send commands. However, dedicated FalkorDB client libraries (Python, JavaScript, Java, Rust) provide higher-level abstractions for easier use.
