Parallel segmented index supporting incremental document and term indexing

A computer program product, the computer program product comprising a computer usable storage medium having computer usable program code for generating an index that supports incremental document indexing and incremental term indexing, the code being configured for:

• receiving an index to a plurality of documents and with respect to a plurality of terms, wherein the index is partitioned in a first dimension by documents to create a first master segment;
• receiving a first term not part of the plurality of terms;
• and
• generating a first slave segment storing an index to the plurality of documents with respect to at least the first term, wherein the slave segment is associated with the first master segment.

A system, comprising:

• a computer processor;
• and
• a memory containing an application program configured to generate an index that supports incremental document indexing and incremental term indexing, which, when executed on the computer processor is configured to perform an operation, comprising:
• receiving an index to a plurality of documents and with respect to a plurality of terms, wherein the index is partitioned in a first dimension by documents to create a first master segment,
• receiving a first term not part of the plurality of terms, and
• generating a first slave segment storing an index to the plurality of documents with respect to at least the first term, wherein the slave segment is associated with the first master segment.
