Elasticsearch is an open source search engine, built on the basis of a Full-text search engine library Apache lucene™. Lucene may be present, whether open source or private, with the most advanced, high-performance and full-featured search engine features of the library. But Lucene is just a library. To take advantage of it, you need to write Java programs and integrate the Lucene packages directly into your Java program. Worse, you need to have a cer

Inverted indexThe inverted index stems from the fact that a record needs to be found based on the value of the property. Each entry in this index table includes an attribute value and the address of each record that has that property value. Because the property value is not determined by the record, it is determined by the property value to determine the position of the record, and is therefore called an inverted index (inverted). A file with an inverted index is called an inverted index file (i
