Nobody?
SOLR-139 seems to be the most popular issue but I don’t think this will be
resolved in near future (this year). Right?
So I will try SOLR-2272 as a workaround, split up my documents in "static" and
" frequently updated"
and join them at query time.
What is the exact join query to do a query like "category:bugfixes AND
body:answer"
matching "category:bugfixes" in doc1 and
matching "body:answer" in doc3
with just returning "doc 1"??
I adopted the fieldnames of
doc 3:
type: out
out_ticketid: 1001
out_body: this is my answer
out_category: other
q={!join+from=out_ticketid+to=ticketid}(category:bugfixes+OR+out_category:bugfixes)+AND+(body:answer+OR+out_body:answer)
Writing this, I doubt this syntax is even possible!?
Additionally I'm not sure if trunk with SOLR-2272 is "production ready".
The only way to do what I want in a released 3.x version is to do several
searches and joining the results manually.
e.g.
q=category:bugfixes -> doc1 -> ticketid: 1001
q=body:answers -> doc3 -> ticket:1001
-> result ticketid:1001
This I way I would lose benefits like faceted search etc. :-\
Any suggestions?

Hi *,
i am a bit confused about what is the best way to achieve my requirements.
We have a mail ticket system. A ticket is created when a mail is received by
the system:
doc 1:
uid: 1001_in
ticketid: 1001
type: in
body: I have a problem
category: bugfixes
date: 201110131955
This incoming document is static. While the ticket is in progress there is
another document representing the current/last state of the ticket. Some fields
of this document are updated frequently:
doc 2:
uid: 1001_out
ticketid: 1001
type: out
body:
category: bugfixes
date: 201110132015
a bit later (doc 2 is deleted/updated):
doc 3:
uid: 1001_out
ticketid: 1001
type: out
body: this is my answer
category: other
date: 201110140915
I would like to do a boolean search spanning multiple documents like
"category:bugfixes AND body:answer".
I think it's the same what was proposed by:
http://www.slideshare.net/MarkHarwood/proposal-for-nested-document-support-in-lucene
So I dig into the deeps of Lucene and Solr tickets and now i am stuck choosing
the "right" way:
https://issues.apache.org/jira/browse/LUCENE-2454 Nested Document query support
https://issues.apache.org/jira/browse/LUCENE-3171 BlockJoinQuery/Collector
https://issues.apache.org/jira/browse/LUCENE-1879 Parallel incremental indexing
https://issues.apache.org/jira/browse/SOLR-139 Support updateable/modifiable
documents
https://issues.apache.org/jira/browse/SOLR-2272 Join
If it is easily possible to update one field in a document i would just merge
the two logical documents into one representing the whole ticket. But i can't
see this is already possible.
SOLR-2272 seems to be the best solution by now but feels like workaround.
" I can't update a document field so i split it up in static and dynamic
content and join both at query time."
SOLR-2272 is committed to trunk/solr 4.
Are there any planned release dates for solr 4 or a possible backport for
SOLR-2272 in 3.x?
I would appreciate any suggestions.
Regards,
Kai Gülzau
