azure search. What if I have a lot of facets
You are correct that this is a current limitation of Azure Search in that you need to pass all the facets in the query string. Please know that we are aware of this and in fact it can be an even bigger issue for customers where they have so many parameters or facets in their query string that it exceeds the max size of the url. For this reason, we are investigating what can be done about this to accommodate this.
I apologize that I do not yet have a date for when this is to be available other than to say it is on our short term roadmap.
