How to create an index with three different properties of an entity in Neo4j?

[alanaxue]

Recently, I encountered a very difficult problem when trying to create an entity relationship on Neo4j. Firstly, there two kinds of entities that they both don't have a any single attribute that could be used as unique index key, But I need to create a relationship between them through mapping their three coordinates rather than by other's properties . So I wander to know if it is possible to create a index for them by using their three coordinates' attributes within Neo4j.
as far as I know, it's seemly that it could only build an index by using one entities' property on Neo4j. Anyway, I hope anyone can tell me if there is a chance to create an index for an entity bu using its three properties ?

their three coordinates' attributes

Hi Alanaxue,

Welcome to the community!!

Please explain what do you mean by "their three coordinates' attributes".

For example, there are two types of entity lists, one is a list of CNV mutations (including chromosome numbers, mutation start points, and mutation end points), and the other is a gene mutation list (it also contains chromosome numbers, mutation start points, and mutation end points). I need to match the corresponding chromosome number first, and then determine whether the mutation range of the gene has an intersection with the chromosome variation. If there is an intersection, I need to create a corresponding mutation entity relationship between them. Due to the large amount of data, I need to build an index with three attributes of the entity for each of them.
