Abstract
A system and method track changes to a document and analyze the changes to the document against a set of predefined queries without re-analyzing the entire document. Hence, after a document has been processed in the system (i.e., had its terms matched against the set of predefined queries), only a small subset of the document needs to be reprocessed and analyzed after changes (i.e., edits) are made. The analysis of the small subset is accomplished by maintaining an incremental-results data set for each document. The incremental-results data set is much smaller than the actual document, only comprising a set of unique words found in a document. After a document is changed, only the words deleted or added to the changed portion are used to update the incremental-results data set.
