The number of times that the search box prompts Baidu search result URL parameters (rsv_sug1)
NameRsv_sug1
Meaning number of times prompted in the search box
Parameter Value
The parameter value is equal to the repeated speed of the keyboard.

When the keyboard repeat speed slows down over the search box prompt delay, the search box prompt may be displayed. At this time, rsv_sug1 = 1. Then, you only need to enter/modify the string at a rate longer than the search box prompt, and the number of prompts in the search box will increase.
Rsv_sug1 is recorded even if the search box prompt is hidden for repeated prompts or for various reasons.
The more times the search box prompts, it means that the prompt search term does not attract users, maybe it is slow for users to enter/modify in the search box.
