Hi,
I have a tree structure of documents, with a document having multiple
parents. This is mapped in the Lucene index using a multivaluefield when
indexing as so:
Document doc = new Document();
doc.add(new Field("uuid","value",MYFIELDTYPE.NOTANALYZED);
doc.add(new Field("parent","parent",MYFIELDTYPE.NOTANALYZED);
doc.add(new Field("parent","parent",MYFIELDTYPE.NOTANALYZED);......
indexwriter.addDocument(doc)
I then need to group the results I get having the most common parent of the
tree as my final result. I am facing a problem as the parent field contains
only the direct parent, this direct parent is stored also in the index in
the same way but when collecting the documents I don't know how to access
it within the collect(ind docID) I can access the fields and group through
inserting into a map but how do a group for example if two elements within
a group have the same parent. Also if a change to the index would be welcome
any input will be grateful
Best Regards,
Taher Galal
