Some languages including Thai, Japanese and Chinese do not have explicit word boundary. This causes the problem of word boundary ambiguity that results in decreasing the accuracy of information retrieval. This paper proposes a new technique so-called character clustering to reduce the ambiguity of word boundary in Thai documents and hence improve searching efficiency. To investigate the efficiency, a set of experiments using Thai newspapers is conducted in both non-indexing and indexing searching approaches. The experimental results show our method outperform the traditional methods in both non-indexing and indexing approaches in all measures.
