Hi Team,
As per the latest updates in the support ticket in Lucid portal we have some
concerns as below
1. The join key id's seem to have to be integers. It says they require
longs, but I am having trouble with anything but an integer as the "from" and
"to" key values.
--regarding the above comment, we need to have these fields as non-numeric
instead of numeric value which was discussed in first call with you.
2. You have to separate this on two collections. This doesn't work as join
does in the same way; it is a function returning a value. That means that
documents that don't match just get a value of zero and still return. That
means all four documents will return if they are all in the same collection.
--starting from the requirement discussion we are emphasizing on the fact that
join needs to be performed between the documents which will reside in the same
core not in different cores.
3. You need a "join" cache in your joined collection.
--could you please explain a bit more on the above like, what
we need to do to have this implementation on our side and what is the
utility/feature of join cache
Also, we tried the vjoin operation with the syntax given by Greg in the ticket
but it is not working as per our expectation.
Thanks,
Sukanta

Hi Team,
Attaching the updated files as per the comments in the ticket. You can now try
the VJOIN operation on the updated files.
It would be also helpful for us if you send the correct VJOIN syntax with the
inputs from the updated files.
Thanks,
Sukanta

Hi Team,
I am attaching all the required files we are using to get the VJOIN
functionality along with the actual requirement statement.
Hope this would help you understand better the requirement for VJOIN
functionality.
Thanks,

Subject: Need help on Joining and sorting syntax and limitations between
multiple documents in solr-4.4.0
Hi Team,
In my project I am going to use Apache solr-4.4.0 version for searching. While
doing that I need to join between multiple solr documents within the same core
on one of the common field across the documents.
Though I successfully join the documents using solr-4.4.0 join syntax, it is
returning me the expected result, but, since my next requirement is to sort the
returned result on basis of the fields from the documents
Involved in join condition's "from" clause, which I was not able to get. Let me
explain the problem in detail along with the files I am using ...
1) Files being used :
a. Picklist_1.xml
--------------------------
<add><doc>
<field name="describedObjectId">t1324838</field>
<field name="describedObjectType">7</field>
<field name="picklistItemId">956</field>
<field name="siteId">130712901</field>
<field name="en">Draft</field>
<field name="gr">Draoft</field>
</doc></add>
b. Picklist_2.xml
---------------------------
<add><doc>
<field name="describedObjectId">t1324837</field>
<field name="describedObjectType">7</field>
<field name="picklistItemId">87749</field>
<field name="siteId">130712901</field>
<field name="en">New</field>
<field name="gr">Neuo</field>
</doc></add>
c. AssetID_1.xml
-------------------------------
<add><doc>
<field name="def14227_picklist">t1324837</field>
<field name="describedObjectId">a180894808</field>
<field name="describedObjectType">1</field>
<field name="isMetadataComplete">true</field>
<field name="lastUpdateDate">2013-09-02T09:28:18Z</field>
<field name="ownerId">130713716</field>
<field name="siteId">130712901</field>
</doc></add>
d. AssetID_2.xml
--------------------------------
<add><doc>
<field name="def14227_picklist">t1324838</field>
<field name="describedObjectId">a171658357</field>
<field name="describedObjectType">1</field>
<field name="ownerId">130713716</field>
<field name="rGroupId">2283961</field>
<field name="rGroupId">2290309</field>
<field name="rGroupPermissionLevel">7</field>
<field name="rGroupPermissionLevel">7</field>
<field name="rRuleId">13503796</field>
<field name="rRuleId">15485964</field>
<field name="rUgpId">38052</field>
<field name="rUgpId">41133</field>
<field name="siteId">130712901</field>
</doc></add>
2) Requirement:
--------------------------------------------
i. It needs to have a join between the files using
"def14227_picklist" field from AssetID_1.xml and AssetID_2.xml and
"describedObjectId" field from Picklist_1.xml and Picklist_2.xml files.
ii. After joining we need to have all the fields from the
files AssetID_*.xml and "en","gr" fields from Picklist_*.xml files.
iii. While joining we also sort the result based on the "en"
field value.
3) I was trying with "q={!join from=inner_id to=outer_id}zzz:vvv" syntax
but no luck.
Any help/suggestion would be appreciated.
Thanks,
Sukanta Dey
