How to extend graphql query search arguments

[Guglielmo89]

Hi,

I'm trying to extend the CIF product list component but I have some problems in customizing the GraphQL query.

I've extended the ProductList model and added custom fields in the query as explained also in this video and guide: 

• https://www.youtube.com/watch?v=sOVtXt-xx4c&t=2s
• https://experienceleague.adobe.com/docs/experience-manager-65/commerce/storefront/developing/customi...

I have also the need to modify the query search arguments with a custom criteria, but I really can't find a guide or an example to do this without having to rewrite the entire component model.

To be more specific, I need to edit the "searchArgs" that are here (SearchResultsServiceImpl) used to generate the graphQL query:

Operations.query(query -> query.products(searchArgs, queryArgs)).toString();

Do I need to write a custom function like "fetchProducts" and build from scratch a product retriever?

Or is there a way to customize the existing query like I've done for the returned attribute set with 

.addCustomObjectField and .addCustomSimpleField

?

To achieve what I need I've edited the CIF components source code and it works, but it seems like an extreme solution to a maybe more simpler problem

Hi @Guglielmo89 ,

Yes, It is recommended to customize and extending core component according to your requirement - similar to the the way you edited source code in CIF component (but to extend rather than changing in core). However, best recommendation is -  whenever possible using existing CIF core component as a starting point for your customization.

• Sling Model delegation - which you can use to customize existing core component.

Based on this you can update searchArgs argument. 

Hope that helps you!

Hi @SantoshSai ,

thank you, I've tried this way extending the ProductList model successfully but the query is executed inside the SearchResultsServiceImpl class that is in fact a Service, so I would have to override the whole "performQuery" method.

Instead I've found this project https://github.com/adobe/graphql-java-generator with which I can define a precise magento schema to generate custom Java classes. With those classes I can rewrite the ProductList model generating my custom graphql query. I know it is not an extension of the existing models and it will require some time initially, but maybe is a solution I can re-use with other custom components in the same project.

Thank you anyway and I hope I've chosen a right solution for this problem.
