      Index

      Index is the short form of property index. An 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

      System properties ID, FROM and TO do not support 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

      Deleting a property will also delete its 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)
