a search query module implemented in hardware of a computing device, the search query module receiving a search query from an entity to search a plurality of digital content;

a sequence data module implemented in hardware of the computing device, the sequence data module obtaining sequence input data describing a sequence of the digital content, with which, the entity has interacted, the sequence of the digital content including a first item from the plurality of digital content with which the entity interacted and a second item from the plurality of digital content with which the entity interacted, the first item being from a first search performed by the entity and the second item being from a second search performed by the entity;

a sequence search module implemented in hardware of the computing device, the sequence search module generating a search result based on the search query and the sequence input data, the sequence search module including a machine-learning module having a localized self-attention module specifying a localized self-attention bias based on a temporal order of digital content within the sequence, the localized self-attention module including a masking-based local encoder implementing the localized self-attention bias, the self-attention bias assigning greater weight to the first item relative to the second item based upon the first item occurring more recently in the sequence than the second item;

a search result representation module implemented in hardware of the computing device, the search result representation module generating a representation of the first item included in the search result, the search result representation module using the greater weight assigned to the first item as a basis for including the representation of the first item in the search result; and

a search result output module implemented in hardware of the computing device, the search result output module outputting the search result having the representation.
