1. A method for deleting duplicate records referenced in an index of a database, each record comprising one or more words and having a unique address, comprising the acts of:
- receiving a record;
determining a fingerprint for the record received;
comparing the fingerprint of the record received with fingerprints of previously indexed records; and
when the comparing act determines that the fingerprint of the record received is the same as at least one of the fingerprints of previously indexed records, identifying the record received as a record to be deleted.

Abstract
A technique for deleting duplicate records referenced in an index of a database is disclosed. In one embodiment, the technique may be realized by receiving a record; determining a fingerprint for the record; comparing the fingerprint of the record with fingerprints of previously indexed records; and, when the comparing act determines that the fingerprint of the current received record is the same as at least one of the fingerprints of any of the previously indexed records, identifying the current record as a record to be deleted.

5. An article of manufacture for deleting duplicate records referenced in an index of a database, each record comprising one or more words and having a unique address, the article of manufacture comprising:
-
at least one processor readable carrier; and
instructions carried on the at least one carrier;
wherein the instructions are configured to be readable from the at least one carrier by at least one processor and thereby cause the at least one processor to operate so as to;
receive a record;
determine a fingerprint for the record received;
compare the fingerprint of the record received with fingerprints of previously indexed records; and
identify the record received as a record to be deleted if, based upon the comparison, the fingerprint of the record received is determined to be the same as at least one of the fingerprints of previously indexed records. - View Dependent Claims (6, 7)

7. The article of manufacture of claim 5, wherein the instructions are further configured to cause the at least one processor to operate so as to:
generate a deleted metaword pair including a location parameter, wherein the location parameter identifies a location of a last word of a page to be deleted.

8. A system for deleting duplicate records referenced in an index of a database, each record comprising one or more words and having a unique address, the system comprising:
-
means for receiving a record;
means for determining a fingerprint for the record received;
means for comparing the fingerprint of the record received with fingerprints of previously indexed records; and
means for identifying the record received as a record to be deleted if, based upon the comparison, the fingerprint of the record received is determined to be the same as at least one of the fingerprints of previously indexed records. - View Dependent Claims (9, 10)
