What is a circuit breaker?The circuit breaker model originates from Martin Fowler's circuit breaker. "Circuit Breaker" itself is a switch device, used in the circuit to protect the line overload, when the circuit has a short circuit, "circuit breaker" can timely cut off the

In order to better typesetting, so the IK word breaker installation restarted a blog post, you can connect to SOLR installation together to view.[Linux] Linux installation and configuration Solr/tomcat/ik Word breaker Detailed example one: http://www.cnblogs.com/wang-meng/p/5814798.html8.

lucene-Word breaker APIorg.apache.lucene.analysi.AnalyzerParser, the core API of the word breaker component, is responsible for building a tokenstream (word breaker) that really handles word segmentation. By calling it the following two methods to get the input text of the word breaker processor.Public final Tokenstrea

SOLR's Chinese word breakerChinese word segmentation in SOLR is not enabled by default, we need to configure a Chinese word breaker. The current available word breakers have smartcn,ik,jeasy, Cook looked through. In fact, mainly two, one is based on the Chinese Academy of Sciences Ictclas Implicit Markov hmm algorithm, such as SMARTCN,ICTCLAS4J, the advantage is the high accuracy of the word segmentation, the disadvantage is that users can not use cus

SOLR itself on the Chinese word processing is not too good, so the Chinese application often need to add a Chinese word breaker to Chinese word processing, Ik-analyzer is one of the good Chinese word breaker.First, version informationSOLR version: 4.7.0Requires Ik-analyzer version: IK Analyzer 2012ff_hf1Ik-analyzer:http://code.google.com/p/ik-analyzer/downloads/listSecond, the configuration stepsDownload the compressed Extract folder after extracting

Write at the beginningIn the Springcloud project, calls are made between services (RPC remote Procedure call-Remote Procedure calls), and when a service that is at the bottom of the calling link becomes unavailable, the request generates a heap that blocks the server thread and even causes the server to crash. A circuit breaker is a way to solve a service unavailability problem.Body StartThis article is based on the third piece of code, the introducti

Normally, we index the data based on the entire field, and the longest field is 10 words, but there's one more thing, if we're indexing an article. At this time how to deal with this field, the word breaker is a good solution to this problem. The SOLR server defaults to providing a word breaker for us, but the word breaker provided by Apache SOLR is not very fr

In a microservices architecture, the service is split into services according to the business, and the service and service can call each other (RPC), which can be invoked with Resttemplate+ribbon and feign in spring cloud. To ensure their high availability, a single service is typically deployed in a cluster. Due to network reasons or their own reasons, the service does not guarantee that 100% is available, if a single service problem, call the service will be a thread blocking, if there is a la

This article is from hereIn the previous concept we have learned that the function of the parser is to divide the sentence into words in terms of semantics. The English segmentation already has the very mature Analyzer: StandardAnalyzer, in many cases standardanalyzer is a good choice. Even you will find that StandardAnalyzer can also be a word for Chinese.But our focus is Chinese participle, standardanalyzer can support Chinese word segmentation? The practice proved to be possible, but the effe

I have been learning Lucene3.5 recently, and I feel that the knowledge inside is really great. Today we will share with you our own to implement a synonym for the word breaker.A word breaker consists of a number of tokenizer and tokenfilter, this article explains that we use these two features to implement their own a simple synonym word breaker, please point out the wrong place.First, design ideasWhat do y

SOLR is a lucene-based Java search engine server. SOLR provides level search, hit highlighting, and supports multiple output formats (including XML/XSLT and JSON formats). It is easy to install and configure, and comes with an HTTP-based management interface. SOLR has been used in a number of large sites, more mature and stable. SOLR has packaged and expanded Lucene, so Solr basically follows the terms of Lucene. More importantly, the index created by SOLR is fully compatible with the Lucene sea

Elasticsearch is a Lucene-based search server. It provides a distributed multi-user-capable full-text search engine, based on a restful web interface. Elasticsearch is developed in Java, as the current popular enterprise-class search engine, used in cloud computing , can achieve real-time search, and has a stable, reliable, fast installation, ease of use and many other advantages, most enterprises are favored.Elasicsearch can be indexed through the terminal, but I do the project with the termina
