Log Analytics query history is one of the most well loved and used features in our UI.
When using Log Analytics frequently, you may create hundreds of queries - all saved in your query history.
We’ve added a new search option to help you quickly find specific items in your query history.
How does it work:
Searching your query history is accessed through the magnifying glass icon in your query history view:

You can search your query text and move between different search 'hit's with the arrows next to the search box.
Summary:
Query history contains a wealth of queries already tried and tested.
Searching query history will help you get to the queries you were looking for faster and with more ease.
