Hello.
Bit late to respond as SP above has provided links but here's some more...
The ? is used by the parser to determine the namespace of the requested resource at the server to process the request ie /search and the & symbols are parameter separator/concatanators, all pretty standard in HTTP requests, and the parameters themselves then follow standard key=value conventions.
So...
The
q= screaming+for+vengeance is the actual search query submitted.
The
oq= screaming+for+...
This is what you had got as far as typing but you then selected the Google suggestion that appeared ie
'screaming for vengeance' and it likely enables the Google search engine to learn and fine tune what it auto suggests.
These are the possibly more interesting ones....
The
aqs=chrome.1.69i57j0l5.7239j0j8[/i] parameter.
The number after the dot seems to be the milliseconds between the first keypress and submitting the query.
So for chrome..69i57j69i60j69i61l2j69i60j0.2486j0j7 it's 2486ms
It always starts with chrome..69i57
What follows seems to be a encoded list of the autocomplete results, when you type a long query this list will get longer.
I am not sure of the last part (j0j7). The last digit seems to indicate whether you picked one of the suggested terms.
and...
The
rlz=1C1CHFX_enNL770NL770.
RLZ identifier[106] Encoded string, according to Google, contains non-identifying information about where Chrome was downloaded from and its installation week, and is used to measure promotional campaigns.[105] Google provides the source code to decode this string.[101]
See
here for more on the use of rlz for promotional campaign stuff.
