Query functions are basic building blocks of requests to Klevu backend. Any amount of them can be placed inside a **KlevuFetch **function as parameters. It is recommended to use multiple query functions inside KlevuFetch instead of multiple KlevuFetch functions. 

Here is list of query functions available. Full listing with code reference can be found from @klevu/core reference.
