Text searching problem has been tackled by variety of traditional string matching approaches over the years. This paper proposes an intelligent text searching technique for information retrieval using probabilistic approach, called Mix Heuristic Algorithm (MHA). In the proposed algorithm, an intelligent programming approach using logical operators has been used that makes this algorithm intelligent and user friendly. We are also presenting a short survey of well-known sequential string matching algorithms. We test MHA implementation and present experimental results for different text matching.
