# Chapter 12. Advanced Graph Querying

This chapter describes advanced graph querying procedures in the APOC library.

The procedures in this chapter enable the querying of graph data when pure Cypher isn’t enough. For more information on how to use these procedures, see:

- Section 12.1, “Path Expander Overview”

  - Section 12.2, “Expand paths”
  - Section 12.3, “Expand paths with config”
  - Section 12.4, “Expand to nodes in a subgraph”
  - Section 12.5, “Expand to subgraph”
  - Section 12.6, “Expand a spanning tree”
- Section 12.7, “Neighbor Functions”
- Section 12.8, “Path Manipulation”
- Section 12.9, “Relationship Querying”
- Section 12.10, “Node Querying”
- Section 12.11, “Parallel Node Search”
