Hi,
The only alternative I can think of would be to store a whitespace seperated list of all ancestors along with a document:
/foo /foo/bar /foo/bar/baz
But this has two drawbacks: Index storage space used, and the cost of indexing (finding all ancestors).
So my question boils down to: Are there any alternatives to solve this scenario in an efficient way?
What about using PhraseQuery, and store the path with all but first path separator replaced by whitespace (i.e. "/foo bar baz one two three"). Then you could query for "/foo bar", "/foo bar baz", and so on...
