1. A computer implemented method for providing in-view and out-of-view request-related result regions for respective results, the method being implemented on a computer system having one or more physical processors programmed with computer program instructions to perform the method, the method comprising: receiving, by the computer system, a user request comprising a request parameter used to filter in or out one or more content items from a first information source and a second information source; causing, by the computer system, a first search for information to be initiated at first information source using the request parameter; obtaining, by the computer system, an identification of at least a first set of results from the first information source based on the initiated search; causing, by the computer system, a second search for information to be initiated at the second information source using the request parameter, wherein the second search is caused to be initiated prior to presentation of the first set of results; obtaining, by the computer system, an identification of at least a second set of results from the second information source based on the initiated second search; generating, by the computer system, a results interface that includes an in-view display region that initially includes the first set of results and an out-of-view display region that initially includes the second set of results; and providing, by the computer system, the results interface to be displayed, wherein the in-view display region is visible at a given time and the out-of-view display region is not visible at the given time.
