It nearly does. In the above example, adding something to an index via curl is
documented as...
curl -HContent-Type:application/json -X POST -d
'http://localhost:7474/db/data/node/123;'
http://localhost:7474/db/data/index/node/my_nodes/foo/bar
... it's not clear what my_nodes is. Is that the index name? As in
graphdb.index(cities)?
And secondly, does each index entry need a key of foo with a value of bar?
As in {'name': 'New York'}?
thanks

Re: [Neo4j] Installing the python bindings ( I think )
Tom,
sorry for the confusion.
my_nodes is the index name (you can several index-names per type (node,
relationship) the default names are nodes and relationships
so for your example it would look like:
curl -Haccept:application/json -HContent-Type:application/json -X POST -d
'http://localhost:7474/db/data/node/123;'
http://localhost:7474/db/data/index/node/nodes/name/New%20York
Sorry, I thought someone updated the wiki, we had the discussion before. Will
do it now.
Michael

Re: [Neo4j] Installing the python bindings ( I think )
Yes, you're right, didn't read that piece of code [ graphdb.index(cities) ] it is graphDb.index().forNodes(cities).add/get you add the name field to the index as otherwise there wouldn't be a distinction where New York appears (e.g. you have a name field and a destination that both can contain New York but you just want to get(name, New York and not those containing it in the destination field. That's the way the Neo4j index API was designed. You also need the property names if you want to do querying as you have to be able to address the individual properties when comparing them to your search values.

Re: [Neo4j] Installing the python bindings ( I think )
So... my curl string for ...
Adding node id 29 to an index called medical with an index property name of
name with a value of Hospitality_Recreation
...looks like this ...
curl -i -s -HAccept:application/json -HContent-Type:application/json -X POST
-d http://localhost:7474/db/data/node/29;
http://localhost:7474/db/data/index/node/medical/name/Hospitality_Recreation;
... which can't quite be right. I'm getting...

Re: [Neo4j] Installing the python bindings ( I think )
Yes because your post data has to be a valid JSON string
so you have to write
-d 'http://localhost:7474/db/data/node/29;'
wrap the double quotes in single quotes, otherwise json just gets http://...29
which it can't parse as a string.
the h that it complains about is from http :)
Cheers

[Neo4j] Installing the python bindings ( I think )
Hello, I'm in a pickle. I KNOW I had neo4j working fine on my computer, but not it complains ... ImportError: No applicable backend found. ... I suspect that I *may* have tidied up my site-packages folder but I'm not sure why it has stopped. I'm now both unable to install JPype (although I think it IS already installed) ... src/native/common/jp_array.cpp:98: error: ‘jvalue’ does not name a type src/native/common/jp_array.cpp: In member function ‘virtual JCharString JPArray::toString()’: src/native/common/jp_array.cpp:107: error: ‘jchar’ was not declared in this scope src/native/common/jp_array.cpp:107: error: expected `;' before ‘res’ src/native/common/jp_array.cpp:108: error: ‘res’ was not declared in this scope error: command '/usr/bin/gcc-4.2' failed with exit status 1 ...and unable to install the python bindings ( on MacOS X)... they error, but I think they are installed OK. I tried using the REST server (which is great) but it doesn't support graphdb.index(whatever) yet. When will the next release of the REST server (with indexing) or the python binding?

Re: [Neo4j] Installing the python bindings ( I think )
What I think is the core of the index REST story is that we need to add the query part of things to it, not just the exact matching (index.get() and index.query()). You can do that easily writing a server plugin, I will try to do it during my next lab day, but the basics go like http://docs.neo4j.org/chunked/snapshot/server-plugins.html Would that help? /peter On Wed, Feb 9, 2011 at 10:25 PM, Michael Hunger michael.hun...@neotechnology.com wrote: Tom, What do you mean with graphdb.index(whatever) the (new) indexing API that is available since 1.2 has the syntax graphDb.index().forNodes(indexName).add(node,key,value) for adding to the index and IndexHitsNode hits = graphDb.index().forNodes(indexName).get(key,value) and this is supported by the REST API, see: http://components.neo4j.org/neo4j-server/milestone/rest.html#Add_to_index Hope that helps Michael Am 09.02.2011 um 16:31 schrieb Tom Smith: Hello, I tried using the REST server (which is great) but it doesn't support graphdb.index(whatever) yet.
