 The most important one here is that I intentionally gave more weight to the Price rather than other filters when we were creating the query, as It acts as a hard constraint, while other attributes like location or amenities adjust the relevance within that boundary. I mean the Price is the most important factor I guess when we are looking out for the real estate.
 
 And as I said earlier, our NLQ engine doesn’t depends on the structured filters, instead it understand the natural language directly.
