Abstract

A system is provided to facilitate tag-based organization of documents. During operation, the system receives an original user query. The system extends the query to include documents with an IN-tag and exclude documents with an OUT-tag. The system then performs a search based on the extended query to indicate a collection of documents which satisfy the extended query. The system further allows a user to add a document to the collection of documents or remove a document from the collection of documents. Next, the system modifies a tagging property of the document.

Claims

1. A method for facilitating tag-based organization of documents, the method comprising:

receiving an original user query in a computer system;

generating an IN-tag and an OUT-tag for the received query, wherein the generated IN-tag and the generated OUT-tag are associated only with a smart folder that includes documents associated with results of the received query; and

wherein the generated IN-tag and the generated OUT-tag are unique to the smart folder;

extending the query to include, in the smart folder, documents which are tagged with an IN-tag associated with the generated IN-tag, and exclude documents which are tagged with an OUT-tag associated with the generated OUT-tag;

performing a search for a collection of documents based on the extended query;

providing a user at the computer system with an interface to add a document to or remove a document from the collection of documents; and

modifying a tagging property of the document at the computer system.

2. The method of claim 1,

wherein if the user adds the document to the collection and if the document satisfies the original query, modifying the tagging property of the document comprises removing an OUT-tag from the document.

3. The method of claim 1,

wherein if the user adds the document to the collection and if the document does not satisfy the original query, modifying the tagging property of the document comprises including an IN-tag in the document.

4. The method of claim 1,

wherein if the user removes the document from the collection and if the document satisfies the original query, modifying the tagging property of the document comprises including an OUT-tag in the document.

5. The method of claim 1,

wherein if the user removes the document from the collection and if the document does not satisfy the original query, modifying the tagging property of the document comprises removing an IN-tag in the document.

6. A non-transitory computer-readable storage medium storing instructions that when executed by a computer cause the computer to perform a method for facilitating tag-based organization of documents, the method comprising:

receiving an original user query in a computer system;

generating an IN-tag and an OUT-tag for the received query, wherein the generated IN-tag and the generated OUT-tag are associated only with a smart folder that includes documents associated with results of the received query; and

wherein the generated IN-tag and the generated OUT-tag are unique to the smart folder;

extending the query to include, in the smart folder, documents which are tagged with an IN-tag associated with the generated IN-tag, and exclude documents which are tagged with an OUT-tag associated with the generated OUT-tag;

performing a search for a collection of documents based on the extended query;

providing a user at the computer system with an interface to add a document to or remove a document from the collection of documents; and

modifying a tagging property of the document at the computer system.

7. The storage medium of claim 6,

wherein if the user adds the document to the collection and if the document satisfies the original query, modifying the tagging property of the document comprises removing an OUT-tag from the document.

8. The storage medium of claim 6,

wherein if the user adds the document to the collection and if the document does not satisfy the original query, modifying the tagging property of the document comprises including an IN-tag in the document.

9. The storage medium of claim 6,

wherein if the user removes the document from the collection and if the document satisfies the original query, modifying the tagging property of the document comprises including an OUT-tag in the document.

10. The storage medium of claim 6,

wherein if the user removes the document from the collection and if the document does not satisfy the original query, modifying the tagging property of the document comprises removing an IN-tag in the document.
