a searching unit that searches the document data using the first search index and the second search index for a user having a special right, and searches the document data using the second search index for a user having no special right
a terminal that transmits the search condition to the document management apparatus and receives the search result from the document management apparatus.
7. A non-transitory computer readable medium storing a program causing a computer to execute a process for managing document data, the process comprising:
concealing confidential information of the document data;
storing, on a first memory, the document data having the confidential data concealed therewithin;
storing, on a second memory, a first search index that is generated for the confidential information included in the document data;
storing, on a third memory, a second search index that is generated for non-confidential information other than the confidential information;
in searching the document data according to an input search condition, displaying a location where the confidential information included in the input search condition is located in a concealment portion in the document data when the document data stored in the memory and including the confidential information included in the input search condition is displayed as a search result, wherein the document data is searched by switching between the first search index and the second search index depending on a right assigned to a user; and
