When a result obtained upon character recognition of an input image is to be used as text data for a search operation, a proper search operation can be performed even if a character different from the actual character image is stored as text data due to a character extraction error in character recognition processing. An information processing apparatus includes an image scanner for inputting image information, OCR software for recognizing the input image, a text information storage section for storing a recognition result, and document search software for assuming addition of an extra character in a designated search word, forming a pattern obtained by deleting a character from the search word, and searching a document using this pattern.

[ What is claimed is:] [1.]1. An information processing method of determining whether a designated character train is included in text information, said method comprising the steps of:forming a pattern including a first number of characters in which at least one character is deleted from the designated character train;dividing the pattern into a plurality of test character trains each including a predetermined second number of characters of the pattern without any other characters, the second number being less than the first number;performing a first determination that determines whether the test character trains are included in the text information;performing a second determination that determines whether the first number of characters are included in the text information for which the first determination has determined that the test character trains are included; andcontrolling output of the text information, for which the second determination has determined that the first number of characters are included, as a search operation result.
