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

Environment: Pyhton3Load module from elasticsearch import elasticsearch Connection eses = Elasticsearch (["172.30.6.12"]) Query res = es.search (index= "Test-index ", body={" query ": {" Match_all ": {}}) # Query request host is ai.baidu.com all information res = Es.search (index=" packetbeat-* ", body={' query ': {' Match ': {' http.request.headers.host ': ' Ai.

The point is to map the name field to two, one to name the index analysis, and the other to not analyze raw, which will not split the phrase New York. So when we do the search, we can do the term aggregation for the Name.raw field and get the number of occurrences in all cities. Term Aggregation's The rest method requests are written as follows

on DocId, which is correct regardless of which index entry is used.So in order to sort the string type field, you need to save the entire string as an index entry and, in order to ensure that the field can be searched, also save the result of the string analyzed (that is, you need to keep the complete string as an entry, while the word is indexed).In the ES for the realization of this function, ES provides a multi-field mapping mechanism, configuration can be configured to achieve the field tha

plugin for managing Elasticsearch.Elasticsearch Official website: http://www.elasticsearch.orgJava environmentI installed the java1.8.x version, not the following steps to install, but one point, you need to set the JAVA_HOME environment variable and path configurationSecond, install ElasticsearchAfter installing the Java JDK, configuring the JAVA_HOME environment variable, you can install the Elasticsearch full-text search engine, first you need to

management is more flexible, a single query can query multiple indexes at the same time. Finally, Elasticsearch has a good scalability, the default support cluster (even if only one node is running), and it is easy to increase the node to achieve capacity expansion and disaster recovery, you can remove nodes at the necessary time to save costs.
