Abstract: Described herein are systems and methods for indexing documents during CPU idle time. The method can include the steps of determining at regular intervals if CPU usage is above a threshold value and pausing the indexing when CPU usage rises above a threshold value. If the CPU usage is below a threshold value the indexing is continued. Unlike traditional document systems, the document database described herein can be updated without interrupting the use of the computer.

Abstract: Described herein are systems and methods for indexing documents in a quasi real-time manner. The method can include the steps of indexing documents and storing document information in a database, registering with an operating system for notification of changes to the documents, and responding to received notification of changes by updating the database to reflect the addition, modification, renaming and/or deletion of documents. Unlike traditional document systems, the document index described herein can be updated without rescanning all the indexed documents.

Abstract: Described herein are systems and methods for indexing documents in a quasi real-time manner. The method can include the steps of indexing documents and storing document information in a database, registering with an extended MAPI layer of an e-mail program for notification of changes to the documents, and responding to received notification of changes by updating the database to reflect the addition, modification, and/or deletion of documents. Unlike traditional document systems, the document index described herein can be updated without rescanning all the indexed documents.
