Thanks. That was what I imagined too. However, I have a test that does: 1. create two nodes (e.g. node 2 and node 3) 2. create a relationship between the two nodes (e.g. rel id 23, type :foo) 3. add the relationship to the foo_rels index, with 2 as the key, 3 as the value (the node ids) on rel id 23. (In REST it's a POST to /index/relationship/foo_rels/2/3 with the URI of the relationship 23 as the body) 4. look up the relationship from the index, returned expected result (GET to /index/relationship/foo_rels/2/3). 5. delete the relationship (id 23) (a DELETE to /relationship/23) 6. look up the relationship from the index again (GET to /index/relationship/foo_rels/2/3), returned empty results ([]).
The result of the test confused me. It appears that the relationship was also removed from the index (as step 6 returned empty array) when it was deleted. Any insights?
