ElasticSearch

问题 How do I add additional attributes to an existing document in Elasticsearch index. $ curl -XPUT 'http://localhost:9200/twitter/tweet/1' -d '{ "user" : "kimchy", "post_date" : "2009-11-15T14:12:12", "message" : "trying out Elastic Search" }' This would create a document in the index. How do I add an attribute to the document? Suppose "new_attribute":"new_value" which would modify the document as "user" : "kimchy", "post_date" : "2009-11-15T14:12:12", "message" : "trying out Elastic Search"

问题 Using Elasticsearch, say I have documents of GeoJSON polygons. I'm using the percolator (ala How to know if a geo coordinate lies within a geo polygon in elasticsearch?) to find if a point lies within a polygon. That works great! Is there any way in Elasticsearch to determine If a point lies outside of all polygons What the closest polygon that to that point? Return that polygon 来源： https://stackoverflow.com/questions/41558123/find-closest-geojson-polygon-to-point-when-point-lies-outside-of

问题 I'm going to have a JSON document where there would be nesting. Example is: { "userid_int" : <integer> "shoes" : { "size_int" : <integer>, "brand_str" : <string>, "addeddate_dt" : <date> }, "shirt" : { "size_int" : <integer>, "brand_str" : <string>, "addeddate_dt" : <date> "color_str" : <string> }, ... } There is no limit on what nested fields could be. For example, I may want a new key "pyjamas" for a particular document. But this is unknown upfront while the index is being created. All I
