Re: indexing directed graph
Thank you Gora in advance! However, I decided to create a bean for indexing something like that: ... String[] vertices String[] edges int[] triple_inx_levels ... So I can search in vertices text & edge text in "vertices & edges" array fields, and I hope to find the relation from triple_inx_levels array, where I will save indexes ot the upper two array in specific order(with some math function, I do not find out yet). I will try in this way, I hope this will enough for me. -- View this message in context: http://lucene.472066.n3.nabble.com/indexing-directed-graph-tp2949556p2960964.html Sent from the Solr - User mailing list archive at Nabble.com.

I seem to remember a discussion on this list some 3-4 months about someone wanting to make a customised Lucene index, specifically for graphs. I believe that he even wrote up a Wiki (?) page on it. Sorry, Dani, I have been busy, and so far my Google-fu has been unable to turn up the thread, or the Wiki page. Will let you know if I come across it. Regards, Gora

Re: indexing directed graph
Thank you for your reply! My target is to make some kind of "relations" between the documents indexed in to the index. So, for the performance reasons, I would like to index the graph created from this relations. In this way I can query/search the subgraph documents by vertices names/text and/or edges name/text -- View this message in context: http://lucene.472066.n3.nabble.com/indexing-directed-graph-tp2949759p2951426.html Sent from the Solr - User mailing list archive at Nabble.com.

Re: indexing directed graph
Absolutely you can index each point or line of the graph with it's own document in Solr, perhaps as a triple. (Sounds like you are specifically talking about RDF-type data, huh? Asking about that specifically might get you more useful ideas than asking graphs in general). But if you want to then figure out if two points are connected, or get the list of all points within X distance from a known point, or do other things you are likely to want to do it with it... Solr's not going to give you the tools to do that, indexed like that. On 5/16/2011 4:52 PM, dani.b.angelov wrote: I am wandering, whether the following idea is worth.

Re: indexing directed graph
You can certainly index it, the problem will be being able to make the kinds of queries you want to make on it once indexed. Indexing it in a way that will let you do such queries. The kind of typical queries I'd imagine you wanting to run on such a graph -- I can't think of any way to index in Solr to support. But if you give examples of the sorts of queries you want to run, maybe someone else has an idea, or can give a definitive 'no'.

[...] There was a discussion earlier on this topic, i.e., how to efficiently store graphs in Solr/Lucene, but IMHO, at the moment, you are better off using a graph database that is specifically adapted for that.
