—This paper summerizes the technical specifications and design principles of an online search tool we developed to help English as a Second Language (ESL) learners in certain aspects of writing. The problem we identified is the confusion caused by either first language interference (L1 interference) whereby literal translation erroneously combines with English words, or because certain words in English come together without a clear rule governing their combination such as collocations. The tool designed employs databases of authentic English texts (corpora) in addition to texts from trusted websites such as governmental and educational websites.
