ElasticSearch is a powerful open source search and analytics engine that makes data easy to learn E.
It can be simply understood as a indexing and retrieval tool. Of course, it has more functions than this.ElasticSearch cons
Use Akka to optimize quasi-real-time systems of Spark + ElasticSearch
In this scenario, the system receives a large number of events every second. Each event contains many parameters, in addition to quasi-real-time data, you must periodically determine whether the combination of each event and event parameter value has exceeded the threshold value set by the system. In this scenario, what kind of solutions should users adopt? Recently, Android Camilo,
Elasticsearch provides the default word divider, which separates each Chinese character, instead of the keyword. For example:
Curl-xpost "http: // localhost: 9200/userinfo/_ analyze? Analyzer = Standard pretty = true text = I am Chinese"We will get the following result:
{Tokens: [{token: textstart_offset: 2end_offset: 6 type: Under normal circumstances, this is not the result we want. For example, we prefer word segmentation like "Chinese", "China"

Fortunately, there are two Chinese Word Segmentation plug-ins written by medcl (one of the first persons studying es in China), one of which is Ik, one is mmseg. The following describes the usage of both of them. In fact, both are similar. First install the plug-in and run the command line:Install the IK Plugin:

Elasticsearch 2.20 entry: Aggregate operations
Aggregations provides the ability to group and collect documents. Aggregation is similar to the group by function in relational databases. In Elasticsearch, you can obtain the aggregate results in an aggregation query and then aggregate them again. This is a very useful function. You can get the results of multiple aggregation through one operation to avoid mul

Previously, all of the downloaded versions were released on the official website, but he did not do a good job in Chinese word segmentation. You need to install the Chinese word divider. Even if you have installed the ik word divider, it cannot be well supported. You need to install some plug-ins and configure them. Fortunately, there is a lazy package of RTF on the Internet.What is
