Gerd Bremer commented on SOLR-2272:
-----------------------------------
Is it possible to sort the join query result?
// first class of documents with refid and pagecount fields;
// a refid field maps to an id field in the second class of documents (1->100,
2->101)
doc1:
----
id:1
refid:100
pagecount:35
doc2:
-----
id:2
refid:101
pagecount:45
// second class of documents with text field
doc100:
------
id:100
text:hello world
doc101:
------
id:101
text: goodbye
Now I would like to select the documents from the first class with field
pagecount sorted descandant, that is {doc2, doc1} and return the mapped
documents with text in the same order that is {doc101,doc100}. Is this possible
with join? I'm looking for an alternative to partial update and this join looks
promising if I can sort and get the mapped result in the same order.
