Optimization of market queries

Hello, I am a web front-end engineer. When using trade, I hope you can optimize the query function. For example, if you select category and rarity in the type filter, can you do a cascading query in the stat filters so that there are no entries that do not enter subcategories? This will increase the efficiency of the query. If the official does not have time to do it, can you provide some data? I am willing to write a tampermonkey plugin to improve this situation
