Abstract

Within an information search system, for plural numbers of databases as being a search target, an index database is built up by virtually unifying the databases of the search target, in relation to an index thereof, and search is conducted onto those databases through that index database. For preceding this process, there is provided a relationship means for relating an index within of the index database to an index of the databases as the search target, within the information search system.

Claims

1. An information search system, comprising:

plural numbers of databases, as a being a search target;

an index database, being built up by virtually unifying the plural numbers of the databases, in relation to an index thereof; and

a relationship means for relating an index within said index database to an index within said databases as the search target, wherein search is conducted onto said databases through said index database, and said index database is build up through the relationship made in said relationship means.

2. The information search system, as described in the claim 1, wherein a portion of said indexes of said index database is changeable into non-display in condition, selectively, when displaying a search result obtained within said index database.

3. The information search system, as described in the claim 1, wherein display can be made on an existence or non-existence of an access qualification to said databases as the search target, when displaying a search result obtained within said index database.

4. The information search system, as described in the claim 2, wherein display can be made on an existence or non-existence of an access qualification to said databases as the search target, when displaying a search result obtained within said index database.

5. The information search system, as described in the claim 1, wherein selection can be made on whether a personal-use database be included or not, within a target of obtaining indexes for said index database, if there are common-use databases to be used in common by a user group of plural numbers of users and also a personal-use database for use by an individual user, within said databases.

6. The information search system, as described in the claim 2, wherein selection can be made on whether a personal-use database be included or not, within a target of obtaining indexes for said index database, if there are common-use databases to be used in common by a user group of plural numbers of users and also a personal-use database for use by an individual user, within said databases.

7. The information search system, as described in the claim 3, wherein selection can be made on whether a personal-use database be included or not, within a target of obtaining indexes for said index database, if there are common-use databases to be used in common by a user group of plural numbers of users and also a personal-use database for use by an individual user, within said databases.

8. The information search system, as described in the claim 1, wherein narrowing on the databases of the search target can be made for an each user, within said databases of the search target.

9. The information search system, as described in the claim 2, wherein narrowing on the databases of the search target can be made for an each user, within said databases of the search target.

10. The information search system, as described in the claim 3, wherein narrowing on the databases of the search target can be made for an each user, within said databases of the search target.
