In the process of building Elasticsearch database, the first use of its recommended Logstash tools to import data, but it is very uncomfortable to use, so you want to use Perl good regular expression to filter the data classification, and then import Elasticsearch, So search Cpan found the Search::elasticsearch module.The module on the cpan of the document writte
Rest interface
Now that we have a functioning node (and cluster), the next step is to understand how to communicate with it. Fortunately, Elasticsearch provides a very comprehensive and powerful rest API that allows you to interact with your cluster using this REST API. Here are a few things you can do with this API:
1, check your cluster, node and index health status and various statistical information2. Manage your clusters, nodes, index data, and
Elasticsearch is a very useful search engine, it is the bottom of the integration of luence, so also inherited the inverted indexing principle. To use elasticsearch here we need a few tools and follow these steps.

Elasticsearch can already be used with big data technology frameworks like yarn, Hadoop, Hive, Pig, Spark, Flume, and more, especially when adding data, using distributed tasks to add index data, especially on data platforms. Many of the data is stored in hive, and using hive to manipulate t
While Elasticsearch can support full-text retrieval in a variety of languages, we don't want to switch to Elasticsearch as the backend database for the time being.Of course, when you can store data in a Web application, write a copy of it to Elasticsearch, but it certainly pollutes the original business logic.In the IT industry, as long as there is demand, there

Elasticsearch is a distributed and extensible real-time search and analysis engine. It can help you search, analyze, and browse data, and often people don't anticipate the need for these features at the start of a project. Elasticsearch's appearance is to re-give the hard disk seemingly useless raw data new vitality.Elasticsearch each individual part is not a new creation. For example, full-text search has long been implemented, statistical systems an
River Machinery of ElasticsearchThe elasticsearch itself provides the river machinery for synchronizing data.Here, you can find the official recommended River now:http://www.elasticsearch.org/guide/en/elasticsearch/rivers/current/But the government did not provide HBase river.In fact, Es River is very easy, is a user packaged jar package, ES is responsible for finding a node. and start the river.

Recently, there is a business demand, that is, the Full-text search keyword query list, thus turning to the learning of ES, but also studied for most of the month, make a note, summed up their learning process.
