Hi Joel,
Thank you for your thoughts. I tried the fetch function, however, the
response does not contain "fl" fields of the "fetch" expression. For the
above example, the modified query is as follows:
fetch(names, select(nodes(emails,
walk="john...@apache.org->from",
gather="to"), node as to_s), fl="name", on="email=to_s")
where "names" is a collection that contains two fields representing pairs
of name and email: ("name", "email")
The response returned is:
{ "result-set": { "docs": [ { "to_s": "john...@apache.org"
}, { "to_s": "johnsm...@apache.org"
},
... { "EOF": true, "RESPONSE_TIME": 33 } ] } }
The response should have an additional "name" field in each document
returned. Any additional thoughts are appreciated.
Best,
A.
