Strict mode for apoc.meta.subGraph

[jexp]

Do you have an example? You mean that the labels given should not just be used as start-nodes but also restricted for end-node-labels? If so, that might make sense in general.

Examples:

Relationships only:

call apoc.meta.subGraph({rels:['CATEGORY_PRODUCT']})

call apoc.meta.subGraph({rels:['CATEGORY_PRODUCT'],strict:true})

Labels only:

call apoc.meta.subGraph({labels:['Category','Product']})

call apoc.meta.subGraph({labels:['Category','Product'],strict:true})

Both:

call apoc.meta.subGraph({labels:['Category','Product'], rels:['CATEGORY_PRODUCT']})

call apoc.meta.subGraph({labels:['Category','Product'], rels:['CATEGORY_PRODUCT'],strict:true})

@jexp do the images make sense? Shall I open a PR?

There is a bug in the base code where the subGraph double-counts a meta relationship from a node to itself. The graph procedure doesn't. I'm still figuring out how to resolve it.

[jexp]

Merged, did you add the images to the docs? Could be helpful.

[ADTC]

No, but I'd rather not use these. I'll make some clean example images.
