Lucene.net Nested Documents support (lucene version 3.4)

[Omri Suissa <om...@diffdoof.com>]

Hi everyone,
We are currently implementing Lucene .net in our solution and we need to
use the Lucene Nested Documents support that was introduce in Lucene
version 3.4
If I understand correctly the current version of Lucene .net does not
support this feature (and other 3.4 features), there is a timeline for the
3.4 porting to .net?

Thank you,
Omri

Hi Simon,
Thanks for the help.
This is my scenario:
My search application allow users to add manual tags to each document, each
tag have a name, type and permissions.
When searching I would like to have the following options:
1) get all the document that contains specific tag (with any type) that I
have permission to view
2) get all the document that contains specific tag with specific type that
I have permission to view

For example if I have 2 documents:
Doc A with tags:
         X (type 1, permissions: everyone)
         Y (type 1, permissions: User1, User2)
         Z (type 2, permissions: User1)

Doc B with tags:
         X (type 2, permissions: everyone)
         Y (type 4, permissions: everyone)
         Z (type 2, permissions: User1)

I'll be able to find A and B when searching for all documents with tag X,
only A if X with type 1 and non of the if tag Z and i'm User2 (and so
on...).

So nested documents could really help me where each tag is a sub document
(like sql JOIN operation).

What can I do using the current capabilities?

Thank you for the help,
Omri

Hi,

I do not have an answer to your explicit question, but this mail group 
could perhaps help you with workarounds using the current functionality. 
Are you after the search functionality (field1:a and field2:b) with 
child documents? Or grouping of the results (the sql equivalent of group 
by)? Return the first 5 entries of every group (like a Google search 
does per site)?
