Managing Graphs Using Indexes

The index management function is added to the graph access page to facilitate index addition, deletion, and search.

Creating an Index

Access the GES graph editor. For details, see Accessing the Graph Editor.
On the Indexes tab of the graph editor, click Create.
Figure 1 Creating an index
In the Create dialog box that appears, set the following parameters:
- Name: Enter a custom index name.
- Type:
  - Memory edition: The options are Global vertex index and Global edge index.
  - Database edition: The options are Global vertex index, Global edge index, Local vertex index, and Local edge index.
  Note: If you select Full-Text/Vector Indexing when creating a graph, the index type can be full-text index, vertex vector index, or edge vector index.
- Label: You can choose to toggle on or off this slider. (This option is not available when the index type is vector index.)
- Label Name: This parameter is available only when Type is Local vertex index or Local edge index.
- Attribute: Only the attributes whose attribute cardinality is of the single-value type are displayed here. Multi-values are not shown. (When the index type is vector index, only one attribute is supported and the attribute type is list.)
  Figure 2 Parameters for creating an index
For a database edition graph, you can create any number of indexes. For a memory edition graph, you can create up to 10 indexes.
Click OK. A dialog box appears, where you can choose whether to go to the task center to monitor the index creation progress.
