Multi-database document search system architecture

A computer system comprising:

• a computer readable storage medium storing instructions;
• and
• one or more processors configured to execute the instructions to cause the processors to:
• generate a plurality of objects and links between objects based at least in part on an ontology;
• store the plurality of objects and links in a first database;
• build an index of the plurality of objects and links;
• store changes affecting the plurality of objects and links in a second database;
• receive a user selection of a first object, wherein the first object represents a document;
• perform a first search, with reference to the index, for links to the first object;
• perform a supplemental search of the second database for changes to any of the links to the first object;
• and
• transmit data for displaying search results determined based at least in part on the first search and the supplemental search.

A searching and indexing method comprising:

• generating a plurality of objects and links between objects based at least in part on an ontology;

• building an index of the plurality of objects and links;
• storing changes affecting the plurality of objects and links in a second database;
• receiving a user selection of a first object, wherein the first object represents a document;
• performing a first search, with reference to the index, for links to the first object;
• performing a supplemental search of the second database for changes in any of the links to the first object;
• and
• transmitting data for displaying search results determined based at least in part on the first search and the supplemental search.
