I want to fetch all available Index in a graph database by Java. Then, I want to fetch all indexed node on them. we don't have any assumption about Index name, the program must be fetch them automatically.
now I can fetch all index name by this line :
for(String s :_graphDb.index().nodeIndexNames()) { }

I want to store all nodes that they indexed by corresponding index to other databases. imagine our database has 1 node that it indexed by a index which is called "PrimaryKey" the key of the index is "PKEY" and the value is "125". we just added this Index by following code:
so when we pars the databases when we analyse this node , the application must be fetch all the node index (PrimaryKey) the key of the index (PKEY) and the value (125). I want to save these information in other databases.

Did you store the information also as property on the node?
Otherwise you'd have to use some low level lucene operations to extract it, you can do it manually with the lucene tool called luke,
It can export this data into xml, see: http://www.getopt.org/luke/ "Export to XML - exports index data and metadata to XML file. This is available both from the GUI and from the command-line."
I don't have the code at hand to read and use the lucene database format programmatically.

Sorry Mahdi,
It's hard to read your question. Do you have any code that shows your

you know I want convert a Neo4j graph to other databases . I convert all the component of a Neo4j database to the target. But I missed index item in the target environment. I want to know, Is there any chance to convert indexed item to the XML or something else ?
for example, imagine we have a graph with two nodes and a relationship.
it is much noticeable that we do not have any assumption about index's name , index key .... we just past a graph to the program or function and it returns the : index name , index key and index value with a specific format

Subject: Re: [Neo4j] Getting existing Indexs By Java
Sorry Peter
you know I want convert a Neo4j graph to other databases .
DN: So that is just silly. Why would anyone want to ever do that? ;-)
I convert all the component of a Neo4j database to the target. But I missed index item in the target environment. I want to know, Is there any chance to convert indexed item to the XML or something else ?
DN: Okay , seriously, there are 6 major classes in Java that work with indexes.
Index<cid:CB3D09EC-41C9-4F33-A0F9-0FB9A5AB0E4C>
IndexHits<cid:5F06BA85-3A76-4680-B9A9-F4FC01E0FF98>
IndexImplementation<cid:AF5B04BF-9FFE-4140-A758-A5DD832C7292>
IndexIterable<cid:734CA358-13EF-4A1C-BBEE-EDF19559230B>
IndexManager<cid:B8802045-7B77-4513-976D-AD2F4173A772>
IndexProvider<cid:8EE1BC97-3231-47F2-A3A4-5E205215BDF3>
I think you why you want, the INdexManager has a lot of methods worth exploring. Whoever designed this class clearly thought of your use case. I will provide a caveat however. I may have misunderstood your request. If not, IndexManager has a method nodeIndexNames<cid:12E4D8AC-F566-4939-AD45-F00C3637849E>()
Which returns an array 9String[]) of all the nodes that are indexes. One returned, you can serialize them into any data format with simple parlous tricks.
Perhaps I did not understand your request?

The application must be worked with all graph, so I don't know the information is stored as node's property.

Mahdi,
If I understand you right, you are looking for a way to export a neo4J
graphics into a format like XML that includes the indexed properties?

DN: So that is just silly. Why would anyone want to ever do that? ;-)
I work on data portability in cloud databases so my portability patterns consist of two migration patterns. as result, it not much silly as you thought ;-)
___________________________________________________________________________ ________________
I only want to export indexed properties but in a specific way , I must to know the owner of those properties.
for example I loop in every nodes. I must to realized that node has some indexed properties. then extract them in XML or something else ( SQL Table).
for example the following code is in Neo4j Document
so I want to get the following output from the above code.* Please notice the function must be work with any graph. that means we do not have any knowledge about index name ("actors"), properties key ("name").*

The only thing I can suggest to you right now is to use the Lucene classes IndexReader and Document
point them to each of the index/lucene/node/* and index/lucene/relationship/* directories read all documents and all fields of each document and use this information.
