Elasticsearch Introduction *Elasticsearch is a real-time, distributed search and analysis engine. It can help you deal with large-scale data at an unprecedented rate.It can be used for full-text search, structured search and analysis, and of course you can combine the three.Elasticsearch is a search engine based on the full-text search engine Apache lucene™, which can be said that Lucene is the most advance
Recently participating in a project design of real-time statistical queries based on Elasticsearch as the underlying data framework to provide large data volumes (billion levels), took some time to learn the basic theoretical knowledge of elasticsearch, organized a bit, hoping to be interested in Elasticsearch The students who want to know have some help. At the
