Hi,
I am using geoserver with neo4j plugin. I have a requirement to show heat
map in geoserver. I got this working by exporting a cypher query result
into Postgres, imported shapefile to postgis and used SQL view of Geoserver
to join the imported data with the shapefile
neo4j version is 1.9.5 w
Brian, this is very much a reasonable request, and would be a great feature
to add. We will take it into consideration.
I think something like this is not so much a question of if but of when and
getting feedback helps decide what to prioritize. That said, there are a
lot of great things we want
When we moved our code to Neo4j 2.0, we ran into a problem caused by a
change in behavior to the TransactionEventHandler
and the way in which Cypher query results are returned in the REST API.
(See this issue https://github.com/neo4j/neo4j/issues/1884).
We were using a TransactionEventHandler i

You should never string format properties that are none.
the only thing that you need to insert into the string is the rel-type all
others, please pass in as parameters.

sorry, the code I have on this program is this: (which is what does not
work)
var relType: string = "EXERCISES";
var props : any = { "props" : { "position" : "Developer", "name" :
"Michael", "awesome" : "true" }};
var statement = util.format("START a=node({fromNodeId}), b=node({toNodeId})

Sean,
the reference node was removed in Neo4j 2.0 so it shouldn't be a problem.
Otherwise just shut down your db, so that id's will be reused and after startup
the next created node will get id 0.

Yes true.
This will only work well if you have only a few nodes with that label in your
db. Otherwise it will fully scan all nodes and load their properties and then
do the check with a regexp all of which is expensive.

Case insensitive searches can be done with regular expressions, e.g.
match (n:Person)
where n.name=~'(?i).*a.*'
return n.name
which would also return results including Andre, andre, Michael

That's possible with a legacy fulltext index which also does case insensitive
matches.

Sorry, no idea. Could you share a runnable unit test that shows that behavior?

Hi,
the problem I have is the following.
using nodejs (javascript) I'm trying to create a relationship between two
nodes of the database Neo4j and this report I'm going to have to create
assign the properties.
This property is written in a variable "props", I am writing under the
lines of code
The `USING INDEX` sub-clause is only for giving Neo4j a hint as to the
index to use. Normally it will work that out for itself, and you shouldn't
need to use it.
In your case, you have two indexes: one on :Person(name) and the other
:Person(job). To use either of those indexes in a query, the C

currently properties is not indexed with a legacy lucene index.
also i want to seach by a single word either properties has multi word :
like node has name : Peter Neubauer
then it can be search by : Peter
as well as by : Neubauer
On Thu, Jan 30, 2014 at 6:56 PM, Michael Hunger <
michael.hun.
if you have indexed the property with a legacy lucene index (fulltext index for
ignoring case) you can do:
> START n = node:Name("Name:john")
> return n;
for multi words I think you have do it like this
> START n = node:Name("Name:john michle")

hi. i am using Neo4j 2.0. I want to search by a properties value with
ignore case and also with like operator.
eg. Node has properties > Name : John Michle
then want to search by : john, John,john Michle etc.
i try :
START n = node:Name("Name=*john*")
return n;
but not get result.

But isn't that code rather doing:

Also shouldn't you also check visited for both loops ? Otherwise you keep
adding the same nodes time and again? Can you add some counters in the 3 loops

Hi Michael,
I'm testing this with the same database, and same query and parameters I've
passed in both the case.
I only change the node no i.e. 2 or 4 in both the cases (means used 2 and 4
in both the cases).
I've copied those queries only which I've used.

Can you share your java code? Do you run the bidirectional pattern matcher?
How much RAM do you have in total? What kind of disk and OS ?
How many :Cable nodes do you have? And how many :Equipment nodes?
How many paths are returned from that query?
Have you considered limiting the max depth?
What do you want to do?

Are you 100% sure you have the same data initially? If one of the start nodes
is not matched it doesn't do anything.
Can you also do a diff for the 2 queries and confirm that they only differ in
the params?
Thanks
