": "not_analyzed" } } Other simple types--long, double, date, and so on-also accept the index parameter, but the corresponding value can only be no and not_analyzed, and their values cannot be parsed. Analysis For string fields of type analyzed, use the analyzer parameter to specify which parser will be used when searching and indexing. By default, Elasticsearch uses the standard parser, but you can change it by specifying a built-in parser,

First, what is Elasticsearch?Elasticsearch is the first choice of open source full-text search engine, it can quickly store, search and analyze massive data. Stack Overflow,github, etc. are in use.Elasticsearch is written in Java and uses Lucene for indexing and searching internally, but it makes full-text retrieval simple, and instead provides a simple, consistent set of RESTful APIs by hiding the complexi

"Quick" lowercase), remove the words (such as disabling words "a" , and "and"``"the" so on), or add words (such as synonyms "jump" and "leap" )Elasticsearch offers many out-of-the-box character filters, Word breakers, and characterization filters. These can be combined to create a custom parser to respond to different requirements. We will discuss this in more detail in the section "Custom Analyzers".Built-in analyzersHowever,

Elasticsearch MySQL incremental sync three-table federated script The above briefly said about the ES synchronization data script, but the actual situation is certainly not as simple as the script in the previous article. For example, I now have three tables, two entity tables, and an association table. The approximate implementation is as follows: The bin direc

Set the configuration parameters in this way: Http.enabled:false, and do not install the head, Bigdesk, Marvel and other monitoring plug-ins, so that the Data node server can only handle the

1.ElasticSearch Simple DescriptionA.elasticsearch is a Lucene-based search server with distributed multiuser capabilities, Elasticsearch is an open source project (Apache License terms) developed in Java, based on a restful web interface that enables real-time search, Stable, reliable, fast, high performance, easy to install and use, and its scale-out capability is very strong, do not need to restart the se

index. Now that we can understand index as a database, type is the table in the database. Document We can interpret it as a row of data in a database table. This is the most basic unit to be indexed. Shards: 1. sharding, if our index data is large, beyond the single file limit of hardware storage (there is a limit under Linux), Then the problem will occur, and it will also affect the speed of the search request.

The loggly Log Management Service uses Elasticsearch as a search engine in many of its core functions. In his article "ElasticSearch vs SOLR", Jon Gifford noted that the field of log management has a higher demand for search technology. In general, it must be able to: Reliable large-scale real-time indexing-for us, processing more than 100,000 log data per second; High-performance, reliable pro
