An example device includes a memory and one or more processors configured to receive an indication of a first set of characters, responsive to determining that a predetermined amount of time has elapsed since the indication of the first set of characters was received, execute a query generated based on the first set of characters, to determine a typing speed associated with the first set of characters, and to generate, based on the predetermined amount of time and the typing speed, an adjusted amount of time, the adjusted amount of time being different from the predetermined amount of time. The processor(s) are further configured to receive an indication of a second set of characters, and responsive to determining that the adjusted amount of time has elapsed since the indication of the second set of characters was received, execute a second query generated based on the second set of characters.
