Using OR along with join query results causing NullPointerException in Solr 4.7.2

[SuReN <su...@gmail.com>]

Hello Lucene/Solr Experts,

I am  getting NullPointerException  while using OR along with the join
results.

Following are the documents and fields configured in my solr server(version
4.7.2).

*brands {id, brand_name}*
*products {id, product_name, brand_id}*

Following are the data indexed

*BRANDS: {1, Apple}, {2, Samsung}, {3, HTC}*

*PRODUCTS: {10, iPhone, 1}, {11, iPad, 1}, {12, Galaxy S3, 2}, {13, Galaxy
Note, 2}, {14, Desire, 3}*

I am trying to get all the products with brand_name is "Samsung" or
product_name is "Desire"

Query which i am trying is

*brand_name:Samsung  OR {!join from=brand_id to=id} product_name:Desire*

But i am getting error saying

ERROR [SolrDispatchFilter] null:java.lang.NullPointerException: while

What is right to use OR along with join query results? I also wanted to
group multiple join results using OR.

Something like following query

*( field1:value1  OR  field2:value2  OR  field3:value3  OR {!join
from=some_id to=some_other_id} field4:value4 OR  {!join from=some_field_is
to=some_other_field_id} field5:value5)*
*AND field7:value7 AND datefield1:{* TO 2015-11-30T14:28:11Z } AND
datefield2:{2015-11-30T14:28:11Z TO *}*

 Please suggest if any other way is there to do this.


Thanks in advance.

Regards,
Suren.
