Hey
You might want to check out SirenDB, set of Lucerne and Solr plugins for advanced nested/tree support. They even have a custom codec for nested docs. We've been pretty interested in it here at OpenSource Connections http://sirendb.com/ Sent from Windows Mail From: kumagirish Sent: Monday, April 14, 2014 11:14 PM To: java-user@lucene.apache.org Hello, i am a new user of lucene i need some help with lucene i have a text file of 300 mb(some times it can be more) which contains data representing a metadata of an Automotive product assembly example Car-->engine -->Chasis -->Body -->Crank Shaft -->CAM Shaft etc. now each first level items can have sub items represented as a tree structure each file i get with such information is huge I need to build a tree structure from this file and represent in a JTree which i have already done For performance reasong what i am doing is populating some of the nodes in the tree structure to a certain level and when ever the user clicks on the expand button i am expanding furthur structure The next problem i need to do is in the text file that we get we have some attribute information of each part i need build a dash board depicting the attribute count say for example:for each part we have 1.Creation date 2.Modified date 3.Release Status 4.Owning user 5.Owning group the stake holders want to see how many parts are created by owning user say "Girish" how many parts belong to Owning Group "Engineering". My problem that i am facing is i am not getting the correct amount of count of nodes under a selected node so that i count metrics as mentioned above and display it in a dashboard I would like to know if it is possible to extract Ids of selected nodes and their children(each node has an unique ID i am planning to index all the attributes including this id ) and send them to Lucene search Please help thanks in advance regards, Girish Durgasi -- View this message in context: http://lucene.472066.n3.nabble.com/Indexing-Huge-tree-structure-represented-in-a-Text-file-tp4131125.html Sent from the Lucene - Java Users mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
