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)
