In the commodity search system based on Solr full-text search technology, this paper uses the third-party Chinese word breaker on the Chinese search information entered by the user segmentation, inquiry commodity index database based on segmenta- tion results, but it ignores the case which the user enters pinyin to search. By analyzing the grammatical structure of Chinese pinyin, the pinyin word segmentation methods are designed, using a proprietary lexicon of e-commerce to construct a Chinese pinyin li- brary, and implementing a commodity search system based onAjax pinyin input prompts to improve the deficiencies in the search in- put method.
