Abstract:
1. A digital processing apparatus comprising: an operating system; and a control logic, in communication with the operating system, comprising a content parsing logic engine in communication with a posting site via the operating system; wherein: the content parsing logic engine generates a content reference comprising a domain name and further comprising query parameters and path parameters based on user parameters; the content parsing logic engine accesses the posing site employing the domain name and the path parameters of the content reference; the content parsing logic engine uses the content reference query parameters to execute a first query on the posing site to extract markup language content; the content parsing logic engine parses the markup language content to generate a map to map item identifiers to respective item data; the content parsing logic engine uses the content reference query parameters to execute a second query on the posting site to extract syndicated content; the content parsing logic engine updates the item data with the syndicated content resulting in a modification of the map; the content parsing logic engine determines a number of search results to present to a user; and the number of search results to present to the user are search results posted no earlier than a maximum look-back interval from a current time wherein the maximum look-back interval is determined by: specifying a first look-back interval; adding a specified correction interval to the first look-back interval; calculating a second interval as a time since a most recent posting from a prior search; and selecting the maximum look-back interval as the shorter of the first interval and the second interval.
