how to search a tree node in lucene?
Hi
i might implement a performant solution for searching a tree node, parent
of a node , children of a node.
a simple idea is
save the path to specific node
and searching prefix/suffix...
Is there a specific solution in the lucene libraries for doing it?

Hi,
The idea here is to use a special Tokenizer that creates multiple tokens of Path-like structures (think of file system paths). If your tree and its nodes are organized like this, you can use it to do the task. Doesn't matter if it's Lucene or Solr. Analyzers and their components can be used in both.
