Unicode Text Searching in Java

Laura Werner - IBM Corporation

Presented by Helena Shih - IBM Corporation

Intended Audience: Software Engineer
Session Level: Advanced

Java uses Unicode as its text storage model, which allows the simultaneous manipulation of text from many different languages and scripts. However, searching through Unicode text can be difficult, because most of the well-known, efficient search algorithms don't map very easily to Unicode. The combining characters, accents, and multi-character collation elements in many languages make matters even worse. This talk will discuss each of these problems and discuss how to solve them using the features available in the Java class libraries. Using successively more complete examples, we will work up to a complete solution that performs efficient, Boyer-Moore searches on multilingual text.
