Request descendant-occurrence-count:

[bit]

As we have child-occurrence-count:, child:, descendant:,
why no descendant-occurrence-count: ?

[void]

child-occurrence-count updates in real-time.

It's too expensive to do this with descendant-occurrence-count:

I'll consider adding support for descendant-occurrence-count with some sort of caching system.

Thank you for the suggestion.

[bit]

child-occurrence-count updates in real-time.

Does child-file-count: / child-folder-count: / child-count: also updates in real-time?
What about sibling-*-count:?
It feels like that the descendant-*-count: not update that quickly. Is it already used some cache? If so, occurrence-count for it is not unacceptable anyway.

[void]

These properties are cached.
Pressing F5 will clear this cache.

They do not update in real-time.

[void]

Everything 1.5.0.1351a adds a descendant-occurrence-count: search function.

I'm adding this for completeness sake.
Results will update in real-time.
Please don't expect good performance when using descendant-occurrence-count:

Example usage:

descendant:mp3 descendant-occurrence-count:>100
