Abstract
One embodiment of the invention provides a method for creating an inverted index. The method comprises receiving documents to be indexed, classifying the documents to determine document types of the documents, and analyzing the documents to identify crucial portions of the documents. The method further comprises generating, based on the analyzing, inverted indexes corresponding to indexing words contained in the documents. Each inverted index corresponding to each indexing word includes a document type tier identifying at least one document type of at least one document containing the indexing word, and the inverted index further includes a crucial list identifying each document which contains the indexing word in a crucial portion of the document if the indexing word occurs in the crucial portions of the documents. The method further comprises selectively caching each inverted index based on whether the inverted index includes a crucial list.
