You can use space as , by use WhitespaceAnalyzer.
By detached mode, I mean the search function and your java system
should be kind of logically separated. From the technical side, a

searching is more like an add-o

Thanks for feedback Chris.
I agree with you. The data set should be flattened out to store inside Lucene
index. The Folder-File was just an example. As you know, in relational
database, we can have more complex relationships. I understand that this model
may not work for deeper relationships.

For this specific question, you can create index on files, search
files that of type image, and from matched files, find the unique
directories(can be done in lucene or you can do it via java).
Of course this does not scale to deeper relationships. Usually you do

As I understand, Lucene has a flat structure where you can define multiple
