Systems and methods of identifying chunks within multiple documents

A computer system, comprising:

• memory;
• one or more processors;
• one or more programs stored in the memory and configured for execution by the one or more processors, the one or more programs including:
• instructions for receiving a search request from a user of the computer, the search request including a plurality of search keywords;
• and
• in response to the search request:
• instructions for identifying multiple resource identifiers in accordance with a first set of predefined criteria for selecting a respective document that satisfies user-specified search keywords from a user, each resource identifier corresponding to a document at a respective data source;
• instructions for retrieving a document from the respective document source for at least one of the resource identifiers;
• instructions for identifying within the retrieved document a chunk by applying a second set of user-specified criteria to one or more candidate chunks within the retrieved document;
• and
• instructions for providing the identified chunk and a link to the identified chunk within the document for display to the user,
• wherein the first set of predefined criteria requires that at least a first subset of the search keywords be found within an identified respective document, and the second set of predefined criteria requires that at least a second subset of the search keywords be found within an identified chunk.

A non-transitory computer readable storage medium having stored therein instructions, which when executed by a computer system cause the computer system to:

• receive a search request from a user of the computer, the search request including a plurality of search keywords;
• and
• in response to the search request:
• identify multiple resource identifiers in accordance with a first set of predefined criteria for selecting a respective document that satisfies user-specified search keywords from a user, each resource identifier corresponding to a document at a respective data source;
• retrieve a document from the respective document source for at least one of the resource identifiers;
• identify within the retrieved document a chunk by applying a second set of predefined criteria to one or more candidate chunks within the retrieved document;
• and
• provide the identified chunk and a link to the identified chunk within the document for display to the user,
• wherein the first set of predefined criteria requires that at least a first subset of the search keywords be found within an identified respective document, and the second set of predefined criteria requires that at least a second subset of the search keywords be found within an identified chunk.
