I think it was not just rootEntity="true". We need to add transformer="TemplateTransformer" and make sure that each entity has some kind of Unique column across all entities e.g. in this case
<field column="doc_id" template="salg_${salgrade.GRADE}" /> is a made up column and this doc_id values should be unique across all entities. template clause is like transformation e.g. doc_id values are made up by prefixing salg_ and values of ${salgrade.GRADE} in the first entity section while in the second entity section, it is using different prefix and different variable to make it Unique. schema.xml have <uniqueKey>doc_id</uniqueKey> and also add following : <field name="deptno" type="text_general" indexed="true" stored="true" required="false" /> <field name="dname" type="text_general" indexed="true" stored="true" /> <field name="loc" type="text_general" indexed="true" stored="true" /> <field name="ename" type="text_general" indexed="true" stored="true" multiValued="true" /> <field name="job" type="text_general" indexed="true" stored="true" multiValued="true"/> <field name="grade" type="text_general" indexed="true" stored="true" required="false" /> <field name="losal" type="text_general" indexed="true" stored="true" /> <field name="hisal" type="text_general" indexed="true" stored="true" /> <field name="doc_id" type="string" indexed="false" stored="false" /> <document> <entity name="salgrade" transformer="TemplateTransformer" query="select grade,losal,hisal from salgrade" > <field column="doc_id" template="salg_${salgrade.GRADE}" /> <field column="GRADE" name="grade" /> <field column="LOSAL" name="losal" /> <field column="HISAL" name="hisal" /> </entity> <entity name="mydept" transformer="TemplateTransformer" query="select deptno,dname,loc from dept"> <field column="doc_id" template="myd_${mydept.DEPTNO}" /> <field column="DEPTNO" name="deptno" /> <field column="DNAME" name="dname" /> <field column="LOC" name="loc" /> <entity name="myemp" transformer="TemplateTransformer" query="select ename,job from emp where deptno=${mydept.DEPTNO} " > <field column="ENAME" name="ename" /> <field column="JOB" name="job" /> </entity> </entity> </document> -- View this message in context: http://lucene.472066.n3.nabble.com/How-do-I-add-another-unrelated-query-results-to-solr-index-tp4128932p4129678.html Sent from the Solr - User mailing list archive at Nabble.com.
