[Baidu Search API] IM Parameter - Time Filter Not Working

[aliayar]

One of our users reached out to report that IM parameter of Baidu search is currently not working.

The Playground:

https://serpapi.com/playground?engine=baidu&q=Coffee&lm=7

The Working Version:

https://www.baidu.com/s?ie=utf-8&f=8&rsv_bp=1&tn=baidu&wd=Coffee&lm=7&oq=Coffee&rsv_pq=c588bc6a00062f27&rsv_t=ad109P4046JsUeJFRnpaK4maauYaWCViFuox3SL6l2F%2B00U0BEuF5R5xZUw&rqlang=cn&rsv_enter=1&rsv_dl=tb&gpc=stf%3D1645438795%2C1646043595%7Cstftype%3D1&tfflag=1

Guidance from our user:

I got that url by...

• going to the url generated by your playground as you had set it up

• clicking on the filter tools (look for the little filter icon on the right under the search bar)

• the tools are dropdown menus and are revealed just as in google when you click on 'tools'

• the left-most dropdown is the one that controls the time.

• I set that to 'within 7 days', which is '一周内', the second option

• that successfully limited the results to the time specified and the first results page had the url above when I did this

By experimenting I found that the arguments that vary as I change the time limit are 'rsv_t' and 'gpc', but obviously the value of these parameters is encoded somehow.

next as we have received a couple of requests about this.
