1. A document management apparatus for managing a plurality of documents registered in a storage device, the apparatus comprising: at least one processor coupled to a memory, the processor being programmed to control one or more of: a user characteristic information acquiring unit configured to acquire user characteristic information including items for identifying a user based on login information of the user when the user logs in; a storage unit configured to store the user characteristic information of the user as attribute information of a document together with the document in the storage device when the user registers the document in the storage device, and store weights representing a relevance between the document and each of the items of the user characteristic information of the user as attribute information of the document; a document acquiring unit configured to acquire a document from the plurality of documents stored in the storage device, wherein the acquired document has at least one item of user characteristic information of a first user who logs in; and a creating unit configured to create a display content to display information according to the user characteristic information of the first user together with an identification for identifying the document acquired by the document acquiring unit, wherein the creating unit classifies the identification based on the weight of each of the items stored by the storage unit, wherein, when the first user instructs to print the document by using the identification, the weight corresponding to the at least one item stored in the storage device is updated, and wherein, when the first user instructs to delete the document by using the identification, the weights corresponding to the items of the user characteristic information of the first user are changed, the identification for identifying the document instructed to be deleted disappears, the document remains in the storage device, and the identification is not displayed based on the changed weights the next time the first user logs in.
