Data retrieval system with controlled access based upon security levels

A document management system and access combination comprising:

• processing circuitry;
• a memory including at least a vector database;
• a plurality of user computers located in distinct geographical locations with there being a plurality of countries among the distinct geographic locations;
• the processing circuitry operable for controlling access to information, and storing documents in the vector database in a plurality of distinct indices with each of the distinct indices carrying a distinct access level based upon at least one of a security level and an appropriate geographic location;
• the processing circuity also operable for receiving a query from one of the user computers for information, and identifying at least one of a security level and a geographic location of the user, and matching the identified at least one of security level and geographic location with at least one of a plurality of aliases, with each of the plurality of aliases providing access to particular ones of the indices in the vector database;
• the processing circuity also operable for accessing the vector database to match the appropriate indices under the identified alias;
• and
• the processing circuity also operable for displaying information from the accessible indices.
