This blog provides an easy way for Elasticsearch to index multiple documents. The support of Bulk API can implement batch add, delete, update and so on once request. The bulk operation uses the UDP protocol, and UDP cannot ensure that data is not lost when communicating with the Elasticsearch server.First, Bulk APIWith the bulk command, the REST API _bulk ends with a bulk operation written in the JSON file,
Optimizing Queries with FiltersElasticsearch supports a variety of different types of queries, which you should all be familiar with. However, the query is not the only option when choosing which document should match successfully and which document should be presented to the user. ElasticSearch Query DSL allows the vast majority of queries that a user can use to have their own identities, which are also nested into the following query types:

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

storage methods are highly favored by current it practitioners. Mongo DB is a good implementation of object-oriented thinking (Oo idea), in Mongo db each record is a document object. The biggest advantage of Mongo DB is that all data persistence requires no developers to write SQL statements manually, and it is easy to invoke methods to implement CRUD operations.ElasticSearchElasticsearch is a Lucene-based search server.
