As suggested in https://support.zendesk.com/hc/en-us/community/posts/115009671788-Perform-a-search-using-string-in-URL I am posting here.
~~~~~~~~~~~~~~~~~~~
I was wondering if there was a way to post a search string using the URL directly.
This would work with the "Manage search engines" feature in Chrome or "bookmark keyword search" in Firefox. You type "z" (or whatever) in the address bar, hit space, paste in a string "123456", and hit enter. This loads a URL of your choosing with the string in it. This is already possible in the API: https://example.zendesk.com/api/v2/search.json?query=123456 but there's no way to modify the URL for In-product Support search: https://abc.zendesk.com/agent/search/1 .
Is there an (undocumented) feature that could do this? It would help our customer service team work much faster (1 pageload instead of several clicks and pageloads). If not, can you put it into your product backlog?
SOLUTION:
As per Yarden A. below:
https://companyname.zendesk.com/agent/search/1?q=xxxxxx where xxxxxx is your search string.
