Exclude loading indicator from input area on query log

Problem Details and Expected Behavior

Exclude loading indicator from data input area on query log, the problem we have to wait around 5 seconds or more till the task done. that may occur when querylog file too large gigabyte size

• Ex: after entered a domain name then need to wait till search complete for enter query type or client
• Ex: if mistyped or entered wrong domain name, again need to wait till search complete for erase or modify the name otherwise necessary to refresh page.

In order to do this properly, we'll need to be able to cancel search queries

I described the same behaviour here: #1184 (comment)
UI should not disable its components during iterative search.
