And finally its almost fine.. :jumping: :jumping: :jumping: Thanks Burnell.
My tables are in Oracle DB. So based on your suggestions the changes made are: 1) In the data-config.xml, <entity name="user" transformer="TemplateTransformer" query="select * from USER"> <field column="rowtype" template="user" /> </entity> <entity name="manager" transformer="TemplateTransformer" query="select * from MANAGER"> <field column="rowtype" template="user" /> </entity> 2) In schema.xml <field name="rowtype" type="string" indexed="true" stored="true" required="true" /> And when I call http://localhost:8983/solr/select/?q=(bob AND rowtype:user)&version=2.2&start=0&rows=10&indent=on only the user entity's values are returned and if I use manager, only the manager's values will be returned... It almost solved my issues.(95%). But I am struck at one point. In the data-config.xml I have an entry like, <entity name="both" transformer="TemplateTransformer" query="select * from USER , MANAGER where USER.userID = MANAGER.userID "> <field column="rowtype" template="both" /> </entity> when i try to search like, http://localhost:8983/solr/select/?q=(150 AND rowtype:both)&version=2.2&start=0&rows=10&indent=on will return zero responces. At the same time if I run http://localhost:8983/solr/select/?q=150&version=2.2&start=0&rows=10&indent=on It will get values from both USER and MANAGER satisfying the condition. Is there any difference in applying transformer in such type of queries.
