That would work in the facet query, but it implies using truncation in the facet.field too, doesn't it? (Assuming you want to group the higher-level facets like "Dir1" rather than getting all the possible paths beginning with "Dir1").
I had assumed I'd have to do something like this: <level1>Dir1</level1> <level2>Dir1/Subdir1</level2> <level3>Dir1/Subdir1/SubSubDir1</level3> Then set up the application to take note of the current level: Top level: facet.field=level1 Level 1: fq=level1:Dir1&facet.field=level2 Level 2: fq=level2:Dir1/Subdir1&facet.field=level3 And so on. But if I don't need to duplicate the info in multiple fields like that, I'd be happier.
