Shalin, Can you please elaborate a little more on the third response *You can send the location's value directly as the value of the text field.* I dont follow. I am adding 'name' and 'age' to the 'text' field through the schema. If I add the 'location' from the program, will either one copy (schema or program) not over-write the other ? *Also note, that you don't really need to index/store the source field. You can make the location field's type as ignored in the schema.* Understood
Thank you for your response.
