Each time a request is sent to the server, we count it as 1 operation. It includes index, autocomplete keystroke, search and etc. For example, if user is attempting to type in “travel agency” to the search bar, per each character user typed there will be a request to our server for suggestion. Often time, user doesn’t need to finish typing the full phrase before they can spot the result they want. For our data, it indicate it takes in avg 5 characters for a user to locate what they are looking for. That is to say, if you divide operation counts by 5, you can roughly obtain the number of search intents from your users.
