在cypher语句中复制Neo4j浏览器自动完成功能 [英] Replicate Neo4j browser auto-complete function in a cypher statement

问题描述

我试图仅使用密码查询来复制neo4j浏览器界面的自动完成"功能.成功的实现将意味着，如果在浏览器中执行查询，则切换自动完成按钮将无效，因为在查询中指定了所有附加关系".

I am trying to replicate the "auto-complete" functionality of the neo4j browser interface using only a cypher query. A successful implementation would mean that if the query is executed in the browser, toggling the auto-complete button would have no effect, as all "additional relationships" are specified in the query.

我使用浏览器为查询创建原型，然后使用RNeo4j来实现它们.理想情况下，我希望RNeo4j结果与浏览器结果(包括自动完成)相匹配.

I use the browser to prototype the queries, then use RNeo4j to implement them. Ideally, I'd like the RNeo4j result to match the browser result including auto-complete.

作为示例，请考虑以下查询:

As an example, consider the query:

`MATCH p = (n:label1 {name:'tom'})-[r*2..3]-(n:label1 {name:'jerry'})
RETURN p`

在浏览器中，关闭自动完成功能后，我只会得到我所要求的(按预期方式)，而打开自动完成功能时，我会得到路径上任何节点之间的所有关系，而这两个节点都不是汤姆"或杰里".

In the browser, with auto-complete turned off, I only get what I asked for (as expected), whereas when auto-complete is turned on, I get all relationships between any nodes on the path where neither node is "tom" or "jerry".

我尝试使用WITH，然后使用第一个MATCH之后的第二个MATCH，但这不会产生我需要的结果.

I have tried using WITH followed by a second MATCH following the first MATCH but this does not yield the results I require.

任何帮助都将不胜感激！

Any help greatly appreciated!

推荐答案

自动完成功能再次调用以获取其当前具有的所有节点ID之间的关系

the autocomplete feature makes another call to get the relationships between all the node ids it currently has

match a-[r]-b where id(a) in [1,2...] and id(b) in [1,2,3...] return r
