对于该语句,Neo4j将启用 NodeByLabelScan 进行节点搜索。 对于场景2,比较高效的查询语句则是: MATCH (n:A_LABEL) RETURN n UNION MATCH (n:B_LABEL) RETURN n 对于该语句,Neo4j将启用 NodeByLabelScan 进行A_LABEL、B_LABEL节点搜索,然后合并查询结果。 How do I rep
Example 5. Multiple labels.示例5:多标签。(4)关系 - Relationship A relationship describes how a connection between a source node and a target node are related. It is possible for a node to have a relationship to itself. 关系用来描述如何连接源节点和目标节点。节点到其自身也可以创建关系。

Use unique labels for indexing within multiple OSM layers. Essentially when adding nodes of a particular label, we also add a label with a unique name for indexing purposes. The unique name is made of the original name plus a hex suffix made of the MD5 hash of the layer name. ...
