Objective: In this paper, the search domain of Farsi printed subwords is intensively reduced by a simple and effective method. Methods: At first, the search space has limited to some selective clusters by using simple extraction feature of horizontal and vertical profiles. Results: The proposed method determined the ratio of the sub word width to the sub word height and confines the search range to this ratio. Finally, the subwords symbol positions are as the same as the input subwords. It is explored according to the symbol position. Conclusion: Applying the proposed model, the search space is effectively reduced. Keywords: Heretical Method, Persian Sub Word, Search Space Reduction
