, not suitable for the current new index warmup API (reference: http://zhaoyanblog.com/archives/764.html) Summarize: 1. When a simple search of existing data, SOLR is faster. 2, when the real-time indexing, SOLR will produce IO blocking, poor query performance, Elasticsearch has obvious advantages. 3. With the increase of data volume, SOLR's search efficiency will become lower, but

Elasticsearch is a distributed RESTful style search and data analysis engine. The biggest difference between the elasticsearch of personal understanding and the traditional relational database is that it can be structured search, full-text retrieval and data analysis. This article briefly describes how to complete the Elasticsearch RESTful

ElasticSearch cluster creation instance I started to research and search, and set up a simple ElasticSearch search cluster on my own virtual machine. I hope it will be helpful.

rules:1) having more fragments can improve index execution capabilities and allow distribution of a large index through machines;2) more replicas can improve search execution and cluster capabilities.For an index, number_of_shards can be set only once, while number_of_replicas can use the Index Update setting API to increase or decrease at any time.Elasticsearch focuses on load balancing, migration, and cluster results from nodes. You can try multipl

It can quickly store, search, and analyze massive amounts of data. It is used by Wikipedia, Stack Overflow, and Github.The bottom of the Elastic is the Open Source Library Lucene. However, you cannot use Lucene directly, you must write your own code to invoke its interface. The Elastic is a Lucene package that provides the operating interface of the REST API and is available out of the box.This article starts from scratch and explains how to use Elast
