Dear Solr Users,
I would like to use solr to do searches on a hierarchical structure (for
knowers CPC and IPC).
Constraint: I use SOLR5.4 and I can't upgrade it.
I succeed to import my xml source file (see at the end of this post for the
xml file)
I succeed to search into.
But I always get the matched items, and I would like to have also "ALL"
parents.
If I delete the item level=4 then I can use this q fl
q={!parent which="c_type:class"}ti:details
f=*, [child parentFilter="c_type=class" childFilter="ti:details"]
BUT, I get only 1 parent level !?
I found id=A01B and id=A01 but not id=A ???!!!
Now if I add the item level=4 and with the same q and fl
Then, I have an error:
Child query must only match non-parent docs
I read all lot of post concerning this problem but not a solution.
Do you think it's possible to do this kind of request to get matched docs
AND all upper-level parents. (i.e A A01 A01B)
Many thanks for your help,
Regards
Bruno
