Bitmap indexing has provided an important database capability to accelerate queries, in large database system. Using bitmap can change index column value into binary characters when searching data into database, according to the theory of database, use the input condition compare with the data that is saved into database. Specially, in large database, the advantage of bitmap index is very excellent, because the values of index column are convert into binary when comparing, not only save the time of searching data but also save the space of storing data into large database system. The common requirement to search for text on the web or in files or database and many solutions exists to solve this problem, the problem becomes harder to solve efficiently when the quantity of rows that need to be searched. At the previous, the searched query use left or doubly truncated wildcards, in large database system. In this paper, using of functional bitmap index offers a flexible and efficient means of indexing data for simply pattern matching on data that length of text is no delimited.
