Generating method, generating apparatus, and recording medium

A generating method comprising:

• selecting a control mode from a first control mode and a second control mode in accordance with whether a document element that includes a predetermined number or more of child elements is present in a document file, the first control mode and the second control mode determining storing locations of data in the document file from a plurality of blocks, the first control mode determining the storing locations of data in the document file for each document element in a hierarchy of the child elements, and the second control mode determining the storing locations of data in the document file for each document element in the hierarchy of the document element that includes the child elements or in the hierarchy higher than the hierarchy of the document element, using a processor;
• dividing the document file into the plurality of blocks by the control mode selected at the selecting, using the processor;
• and
• generating, for each block obtained by being divided at the dividing, index information indicating whether each of the blocks includes predetermined character information, using the processor.
