Hello,
I would like to use SOLR to index the Cooperative Patent Classification,
The CPC has a hierarchical structure and it can have more than 20 level.
It's a basic structure without Type of nested doc.
i.e:
A -> A01 -> A01B -> A01B3/00 -> A01B3/40 -> A01B3/4025 .
A -> A01 -> A01L -> A01L1/00 -> A01L1/012 -> A01L1/0125 .
B -> B05 -> B05C -> B05C10/00 -> B05C10/87
Important: Each "Code" has a Definition (free text used to explain the
code).
A record is: Code + Definition
- I already indexed this CPC structure with a XML format it works fine.
- With this kind of structure I can't set a type of nested doc.
- A keyword that a user search can be found in several levels (parent and
child)
So, my tests:
If I set a field named "typedoc" with "parentDoc" or "leaf",
I'm facing an error when I used ParentFilter, ChildFilter, etc.
"Child query must only match non-parent docs"
q={!parent which="typedoc:parentDoc"}ti:details
fq=*,[child parentFilter="typedoc:parentDoc" childFilter="ti:details"]
I need to have the whole structure when I do a query. I mean, I need to have
all parents until level=1
My question is:
Is someone have already indexed and used this kind of structure ?
All information I found use typedoc field.
Thanks for your help !
Cordialement, Best Regards
Bruno
