1. A computer-implemented method, comprising: receiving an input entered in a search engine query input field by a user; selecting one or more second query suggestions, wherein the second query suggestions are search queries previously submitted by other users of the search engine and not by the user; selecting one or more first query suggestions, wherein the first query suggestions are search queries previously submitted by the user; determining a respective score for each first query suggestion and each second query suggestion, wherein determining a respective score for each first query suggestion comprises determining the respective score for each first query suggestion based on one or more of the following: a number of times the first query suggestion was submitted as a query by the user, a frequency of submission of the first query suggestion as a query in a specified time period by the user before receiving the input, a time of the most recent submission of the first query suggestion as a query by the user, or a multiplication of the number of times the first query suggestion was submitted as a query by the user with the frequency of submission of the first query suggestion as a query in a specified time period by the user before receiving the input; ranking the first query suggestions and the second query suggestions according to the respective scores; identifying from the first query suggestions and second query suggestions one or more selectable suggestions to the input based on the ranking; and providing the one or more selectable suggestions for display in a user interface for possible selection by the user, wherein the first query suggestions in the selectable suggestions are rendered in the user interface with visual features distinct from visual features of the second query suggestions in the selectable suggestions.
