Hi,
I have the following data model:
1. Document (fields: doc_id, author, content)
2. Each Document has multiple attachment types. Each attachment type has
multiple instances. And each attachment type may have different fields.
for example:
<doc>
<doc_id>1</doc_id>
<author>john</author>
<content>some long long text...</content>
<file_attachments>
<file_attachment>
<attach_id>458</attach_id>
<attach_text>SomeText</attach_text>
<attach_date>12/12/2012</attach_date>
</file_attachment>
<file_attachment>
<attach_id>568</attach_id>
<attach_text>SomeText2</attach_text>
<attach_date>12/11/2012</attach_date>
</file_attachment>
</file_attachments>
<reply_attachments>
<reply_attachment>
<reply_id>345</reply_id>
<reply_text>SomeText</reply_text>
<reply_author>Jack</reply_author>
<reply_date>22-12-2012</reply_date>
</reply_attachment>
<reply_attachment>
<reply_id>897</attach_id>
<reply_text>SomeText2</reply_text>
<reply_author>Bob</reply_author>
<reply_date>23-12-2012</reply_date>
</reply_attachment>
</reply_attachments>
I want to index all this data in solr cloud.
My current solution is to index the original document by its self and index
each attachment as a single solr document with its parent_doc_id, and then
use solr join capability.
The problem with this solution is that I must index all the attachments of
each document, and the document itself in the same shard (current solr
limitation).
This requires me to override the solr document distribution mechanism.
I fear that with this solution I may loose some of solr cloud's
capabilities.
My questions are:
1. Are my concerns regarding downside of overriding solr cloud's
out-of-the-box mechanism justified? Or should I proceed with this solution?
2. If I'm looking for another solution, can I somehow keep all attachments
on the same document and be able to query on a single attachment?
A query example:
Retrieve all documents where:
content: contains "abc"
AND
reply_attachment.author = 'Bob'
AND
reply_attachment.date = '12-12-2012'
Thanks.
