Abstract
Provided is a database search device that, when searching an external database, efficiently executes any search command even if the usable search commands are restricted. The database search device comprises: a search command separating unit that separates input search commands into a first search command that can be executed in a prescribed database and a second search command that cannot be executed in the prescribed database; and a search command execution unit that provides the search results obtained by executing the second search command on the search results obtained by executing the first search command in the prescribed database, as the search results for the input search command.
Claims10
A database search device comprising:
- a search command separating unit that separates an input search command into a first search command that can be executed in a predetermined database and a second search command that cannot be executed in the predetermined database;
- and
- a search command execution unit that provides a search result obtained by executing the second search command on a search result acquired by executing the first search command in the predetermined database, as a search result for the input search command.
A database search method comprising:
- separating an input search command into a first search command that can be executed in a predetermined database and a second search command that cannot be executed in the predetermined database;
- and
- providing a search result obtained by executing the second search command on a search result acquired by executing the first search command in the predetermined database, as a search result for the input search command.
A non-transitory computer readable storage medium recording thereon a program, causing a computer that controls a database search device to execute:
- search command separating processing that separates an input search command into a first search command that can be executed in a predetermined database and a second search command that cannot be executed in the predetermined database;
- and
- search command execution processing that provides a search result obtained by executing the second search command on a search result acquired by executing the first search command in the predetermined database, as a search result for the input search command.
