    Index

    Index has the same name and schema with the property it references.

    Show Index

    Returned table name: _nodeIndex, _edgeIndex
    Returned table header: name | properties | schema | status (Name, properties, schema and status [creating|done] of index)

    Syntax:

    // To show all indexes in the current graphset (node indexes and edges indexes in separate tables)
    show().index() 
    
    // To show all node indexes in the current graphset
    show().node_index()
    
    // To show all edge indexes in the current graphset
    show().edge_index()
    

    Create Index

    Syntax:

    // To create index for a certain property of a certain node schema in the current graphset
    create().node_index(@<schema>.<property>)
    
    // To create index for a certain property of all node schemas (if has) in the current graphset
    create().node_index(@*, <property>)
    
    // To create index for a certain property of a certain edge schema in the current graphset
    create().edge_index(@<schema>.<property>)
    
    // To create index for a certain property of all edge schemas (if has) in the current graphset
    create().edge_index(@*, <property>)
    
    // To create index for multiple node/edge properties using the four methods above
    create()
      .node_index(@<schema>.<property>)
      .node_index(@*, <property>)
      .edge_index(@<schema>.<property>)
      .edge_index(@*, <property>)
      ...
    

    Example: Create index for @card property balance

    create().node_index(@card.balance)
    

    Example: Create index for @transaction property amount

    create().edge_index(@transaction.amount)
    

    Drop Index

    Syntax:

    // To delete index for a certain property of a certain node schema from the current graphset
    drop().node_index(@<schema>.<property>)
    
    // To delete index for a certain property of all node schemas (if has) from the current graphset
    drop().node_index(@*, <property>)
    
    // To delete index for a certain property of a certain edge schema from the current graphset
    drop().edge_index(@<schema>.<property>)
    
    // To delete index for a certain property of all edge schemas (if has) from the current graphset
    drop().edge_index(@*, <property>)
    
    // To delete index for multiple node/edge properties using the four methods above
    drop()
      .node_index(@<schema>.<property>)
      .node_index(@*, <property>)
      .edge_index(@<schema>.<property>)
      .edge_index(@*, <property>)
      ...
    

    Example: Delete the index for @card property balance

    drop.().node_index(@card.balance)
    

    Example: Delete the index for @transaction property amount

    drop.().edge_index(@transaction.amount)
