Based on an in-depth study of Lucene full-text retrieval and indexing development kits, this paper designs a multi-indexer indexing scheme, which effectively reduces indexing time and improves indexing efficiency. When establishing an inverted index, the search efficiency of chemical vocabulary is improved by optimizing the term sorting process in the index table and improving the sorting method. Adding different types of weights to the documents to be indexed can improve the accuracy of document retrieval and meet the needs of chemical professional search engines.
