To retrieve all recurrence of the pattern in offline
text, pattern searching techniques are used. Two processes would
be carried out in our approach, first process would be
preprocessing and second process would be searching process.
Pattern searching algorithms consists of problems with searching
space and time overhead. The efficiency of proposed algorithm is
improved by adopting binary search tree and SDBM hash
function techniques. These techniques are applied to make fast
the search time to find a unique key for each pattern in the text.
