Claim 0:
1. A computer-implemented method for creating one or more indexes for information retrieval, the method comprising:
parsing, in computer memory, a document that includes text to identify a unique expression in the text of the document using hinting information that is embedded in the document to identify the unique expression in the document;
creating a plurality of indexes for the document by applying at least two different analysis methods to the text of the document, wherein creating the plurality of indexes comprises:
switching between a first analysis method and a second analysis method based on identification of the hinting information in the document, wherein, in response to identifying an instance of the hinting information, the first analysis method is performed to create an index in a first set of indexes for the document that index the unique expression in the text of the document, and switching to the second analysis method to create one or more indexes in a second set of indexes for the document that index one or more sequences of words in the text of the document that are between the instance of the hinting information and one of a next instance of the hinting information and an end of the text,
wherein the one or more sequences of words do not include the unique expression, wherein the second analysis method is not performed on the unique expression, and wherein the second analysis method is different than the first analysis method; and

storing the created plurality of indexes in the memory for use in information retrieval.
