Help for Aimeos

I didn't do anything in the code. I am using Aimeos admin panel to add the attribute. I found one thing that when i added the attribute in the product characteristics. It doesn't reflect in mshop_index_attribute table.

I am using the JSONAPI. Where can i add this code?

I created a attribute and add in a product characteristics and in options. But i am not able to search that particular product with that attribute id. If list the attribute is listing with product.
Can you tell me what is the reason?

Hi Team, Here i wan to filter the product according to the attributes using JSON API. Can i list the attribute using attribute type? in
