SOLR DIH在同一个MySql表上添加具有多个查询的文档

Question

I am Kind of Noob in Solr, Iam stucked in a Situation where I want to Make a full import to a Same Document entity, using multiple queries on SAME Table based on diffrent conditions using Solr DIH . So it can be achieved ?

My Problem (What I want to Do) :

Say for eg , I want to define my data import schema like this , to Index entity with the data from TABLE A , Multiple Times based on different conditions , is the below format possible?

   <entity name="ITEM" query="select * from TABLE A where condition 1  And Some different sets of rules">
       <field column="ID" name="id" />
       <field column="NAME" name="name" />
       <field column="MANU" name="manu" />
       <field column="WEIGHT" name="weight" />
       <field column="PRICE" name="price" />
       <field column="POPULARITY" name="popularity" />
       <field column="INSTOCK" name="inStock" />
       <field column="INCLUDES" name="includes" />
   </entity>

   <entity name="ITEM" query="select * from TABLE A where condition 2  And Some different sets of rules">
       <field column="ID" name="id" />
       <field column="NAME" name="name" />
       <field column="MANU" name="manu" />
       <field column="WEIGHT" name="weight" />
       <field column="PRICE" name="price" />
       <field column="POPULARITY" name="popularity" />
       <field column="INSTOCK" name="inStock" />
       <field column="INCLUDES" name="includes" />
   </entity>

Defining several entities with different queries that import into the same collections should work as you write. You probably want different name=""-s for them, though (if you have to ask "Does this work?", just try it). You can use a UNION to solve the first case if two different entities does not work for what you want to do.
