There has been an interesting phenomenon in the IT community over the past few years. Many new technologies have emerged and embraced "big data" immediately. A little bit older technology will also add big data to their own features, to avoid falling too far, we see the different technologies of the marginal ambiguity. If you have search engines such as Elasticsearch or SOLR, they store JSON documents, MongoDB has JSON documents, or a bunch of JSON do
Elasticsearch IntroductionElasticsearch 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 advanced and efficient full-featured open source searc

2. Create a querybuilder.QueryBuilder you can set a query for a single field, or you can set up multiple fields.e.g.1: Query hibernate The
I briefly introduced Elasticsearch in play with elasticsearch. In this article, we still do some basic learning about how to perform CRUD in Elasticsearch? Suppose we are creating an application similar to Weibo. Let's call it kiwi first. Kiwi is composed of messages. In kiwi, a message is called a ksay

Elasticsearch IntroductionElasticsearch (ES), an open source search engine based on Apache Lucene (TM), can be considered as the most advanced, best-performing and most functional search engine library in the world, whether in open source or proprietary domain.However, Lucene is just a library. To play a powerful role, you need to integrate it into your app using C #. Lucene is very complex, and you need to understand the search knowledge to understan

Elasticsearch is a distributed, restful search and Analysis server, like Apache SOLR, which is a lucence-based index server, but I think the advantage of Elasticsearch versus SOLR is:
Lightweight: Easy to install, download the file after a command can be started;
Schema Free: You can submit JSON objects of any structure to the server, using Schema.xml to specify the index structure in SOLR;

Why doesn't my search *foo-bar* match foo-bar ?
Why do you add more files to compress indexes (index)?
Why does
Before you introduce the usage of Elasticsearch, let's talk about why you should use it. First of all to learn the search engine, certainly inevitably have heard LUCENE,SOLR and Elasticsearch are based on it. Spinx many articles, but the database is too intrusive (plug-in mode). Elasticsearch is one of the most popular distributed search engines of the moment. SO
First, IntroductionElasticsearch is an open source, distributed, restful search engine built on Lucene. Designed for cloud computing, it can achieve real-time search, stable, reliable, fast, easy to install and use. Supports data indexing using JSON with HTTP.Lucene is just a framework to take advantage of its functionality, to use Java, and to integrate Lucene into the program. To make things worse, Lucene is very complex and requires a lot of learning to understand how it works.Elasticsearch u

Working Mechanism of ElasticSearch
Like Solr, ElasticSearch is an enterprise-level search engine that is based on Apache Lucene and has high reliability.
Some concepts in ElasticSearch correspond to relational databases. For example, a database is called an index in ES and a table is called a Type in ES.
The specific relationship is shown in the table below.

The system is Windows Server 2003.Elasticsearch is a stable, distributed, restful search engine based on Lucene. In fact, the so-called restful is that it provides a URL for you to call (indexing and retrieval), but it is too brutal to use it directly. Therefore, it also provides a series of client packages, which are equivalent to encapsulating the curl request, the languages supported by the client package include Java, PHP, Python, Ruby and Perl, a
