Hey Peter, using the example of my original email, this is the

A single GET query returns the name data (as raw json) as:

Have you checked logs? What was the failure you saw?
In an non-clean shutdown, the next time it starts it would try to recover
the indicies. It takes time, and if the timeout value you set (for starting
the service) is less than the time needed for the recovery, the server would
have trouble

Guys,
Do you have a JSON string you would use to set properties on a node? Can
then update a test with it and check.

Hi Marko and Gremlin gurus:
Currently I'm doing the following in my own code with multiple requests to
the standalone neo4j server. I wonder if it's possible to achieve in one
gremlin query/script so that I can post the gremlin query to the server as 1
request and done. What I'm trying to achieve
I have nodes with data properties with unicode (Chinese/Japanese) characters
such as:
{uid = 12345, name = 例子}
I index such nodes with their id, so that by doing this (where users_index
is the index, uid is the key, 12345 is the value):
GET to /index/node/users_index/uid/12345
I can get back
with the client code not understanding unicode. Is there
something you could use as a baseline to rule the database out eg maybe the
web admin?

Hey guys,
When a relationship gets deleted, will it be removed from the index
automatically? My test shows yes, but I want to be absolutely certain.
For example, a relationship :foo exists between node A and B and it's
indexed on the foo_rels index with key node_a's id and value node_b's id.

It happened again and I'm pretty sure there was no other server process

Also this time when it crashed I saw this line in the console log (not

disabled
When I tried to restart,

Also one thing I forgot to mention was that for a few occasions that the
server was able to start after a few tries after the error; other times I
tried enough times and since it's my dev machine so I decided to clear/move
the database and restart (which has always led
