Some aspects include determination of a first set of attribute-value pairs associated with an entity, the first set of attribute-value pairs comprising a plurality of attributes and first values, and respective ones of the first values corresponding to each of the plurality of attributes, determination of a second set of attribute-value pairs associated with the entity, the second set of attribute-value pairs comprising the plurality of attributes and second values, and respective ones of the second values corresponding to each of the plurality of attributes, and generation of index entries, each of the index entries indicating one of the first set or the second set of attribute-value pairs, an attribute of the indicated set of attribute-value pairs, a value of the attribute of the indicated set of attribute-value pairs, and the entity. In some aspects, a first set of attribute-value pairs associated with an entity is determined, the first set of attribute-value pairs comprising a plurality of attributes and first values, and respective ones of the first values corresponding to each of the plurality of attributes, a second set of attribute-value pairs associated with the entity is determined, the second set of attribute-value pairs comprising the plurality of attributes and second values, and respective ones of the second values corresponding to each of the plurality of attributes, one of the plurality of attributes is determined to be mono-valued, a priority of the first set of attribute-value pairs is determined to be higher than a priority of the second set of attribute-value pairs for the determined attribute, and a first value associated with the determined attribute from the first set of attribute-value pairs is added to a profile of the entity, while a second value associated with the determined attribute from the second set of attribute-value pairs is not added to the profile of the entity.
