In a computing system, an input that a user makes under guidance of a graphical user interface may be received. The input specifies several query portions to be used in searching a data repository in the system. Each of the query portions comprises a value entered by the user that is associated with any of several attributes of objects in the repository. The input does not specify a logical operator between any of the query portions. A search query is generated for searching the repository by: (i) determining whether any of the query portions have a common attribute, and associating any such query portions with each other into a new query portion using a logical OR operator; and (ii) thereafter associating any of the query portions that were not associated in step (i), and any new query portion formed in step (i), with each other using a logical AND operator.
