This essentially Lucene analyzer CHAIN,SOLR is just handy: you can link tokenizer and filter by configuring an XML file. We sometimes need to use this chain in our own code.

Getting started with Elasticsearch-Installation and getting started with elasticsearch Elasticsearch is a real-time distributed search and analysis engine that allows you to explore your data at a speed and scale you have never used before. It is used as a combination of full-text search, structured search, and analysis. -- Authoritative guide

An interesting trend have been developing in the IT landscape over the past few years. Many new technologies develop and immediately latch onto the "Big Data" buzzword. And as older technologies add "Big Data" features in an attempt to keep up with the Joneses, we is seeing a blurring of t He boundaries between various technologies. Say you have search engines such as ElasticSearch or SOLR storing JSON docu

Otherwise the error will be made and the subsequent s

Finally, I found the distributed search framework of elasticsearch. As soon as I read it, I thought it was the same. Basically all the features I want include distributed search, distributed indexing, Zero Configuration, automatic partitioning, automatic indexing load, automatic discovery, and restful APIs. So I started to use it, deployed four machines, and imported the index. I set the partition to 3, that is, the index is divided into three parts,

Full-text search engine Solr, full-text solr Solr is an independent enterprise-level search application server that provides APIs similar to Web-service. You can submit an XML file of a certain format to the search engine server through an http request to generate an index. You can also submit a search request through the Http Get operation and obtain the return

Scattered cents, in the previous article on the overall introduction of Elasticsearch, then this article we look at how to install, deploy ES, and how to install ES several more commonly used plug-ins.ES installation and deployment, is very simple and convenient, at least this point between ES and SOLR, can be clearly reflected, SOLR installation is to rely on th

As the search engine function has a large number of functional requirements that require search engines in the portal community to improve user experience, there are currently a centralized solution for implementing search engines: Implement intra-site search by using Lucene's own encapsulation. Large workload and scalability, not used. Call APIs of Google and Baidu to implement intra-Site Search It is too dead to bind with a third-party search engine to meet the business expansion nee

In the process of starting to access ES encountered a variety of wonderful problems.1. On-line various versions of the start-up mode is confusing to know how to start. Simple and rude--execute directly in the bin directory of ES./elasticsearch//display start, CTRL + C can stop, such as to operate, change the terminal./elasticsearch-d background boot, can continue operation at the current terminal//backgroun

Our products require full-text search functionality, and back-end data storage primarily uses MySQL + MongoDB, where the content that needs to be retrieved is in MongoDB.MongoDB itself is self-featured with text indexing, but it does not support Chinese. The technology industry has specialized, MongoDB is the data storage application, then the full text search uses the specialized full-text search engine bar.Some of the pre-selected contestants are: SOLR
