Query Log - text in 'Search box' needs "lock"

I read many feature requests regarding "Query Log". Very popular feature, and used extensively for many varied reasons.

Here is my feature request:

Goal : After installing an app to my iPhone, or installing an app to the PC, for example, before I run it for the first time, I would like to see to who/where is this app talking to, but one thing I would like to do is to lock my search text, at least for the time I do my research.

Whatever I type in the search box is gone after I go and come back from that page. So I have to type it again. And again. Perhaps a check-mark box on the left of the search box that locks the text?

Thanks for reading.
