Fetch FAQs from FD knowledge base on basis of some tag that can associated

Hi 

I was looking for if there is a way to achieve below two things 

1. Search faq articles from knowledge base with some filter in it . For example if i have multiple products whose FAQs are stored in the same account and i want to use the search API of FAQs using some filter that will only fetch FAQs with that particular filter ( I saw that Fresh-chat mobile SDK offers this as solution but does not have APIs associated with it) 

2 . Use FD knowledge base similar to how FC knowledge base is created in SDK (with all the filtering capabilities that they have )
