Elasticsearch updating events ents

Updating documents to index in ES is not a simple task. We have to keep an eye on it.

It is well known that restful lattice uses the dynamic words of HTTP to update the website, so does es.

Note that there are two ways to update elasticsearch.

• Update the entire docment (replace, override)
• The root operator updates a field (count + = 3, append string, adding elements for the Data Group, excluding the field)

// Update a field in the root queue
$ Curl-xpost 'localhost: 9200/test/type1/1/_ Update'-d' {"script": "CTX. _ source. counter + = count "," Params ": {" count ": 4 }}'

We usually encounter a field to be updated that does not exist, so we can use upsert to set the default value.

$ Curl-xpost 'localhost: 9200/test/type1/1/_ Update'-d' {"script": "CTX. _ source. counter + = 1 "," upsert ": {" counter ": 0 }}'
