Choosing the fields that we want to return With the use of the fields array in the request body, Elasticsearch allows us to define which fields to include in the response. Remember that you can only return these
The index is employed for searching. Indexed fields are transformed during analysis, and cannot retrieve the original data when necessary. Store implies the data stored by Lucene, which will again return when necessary. Stored fields are not searchable. What is an Analyzer in ElasticSearch? While ...
Please refrain from using HTTP level rules to protect certain indices or limit what people can do to an index. The level of control at this level is really coarse, especially because Elasticsearch REST API does not always respect RESTful principles. This makes of HTTP a bad abstraction level t...
Setting slices to auto will let Elasticsearch choose the number of slices to use. This setting will use one slice per shard, up to a certain limit. If there are multiple sources, it will choose the number of slices based on the index or backing index with the smallest number of shards. ...

In Elastic search, we can create certain tags across all indices across all indices and all types. URI search:A search request is executed using a URI by providing requested parameters. Request body search:A search request need to be executed by a search DSL. It includes the query DSL withi...
Since we are searching across multiple fields, we may want to boost the scores in a certain field. In the contrived example below, we boost scores from the summary field by a factor of 3 in order to increase the importance of the summary field, which will, in turn, increase the ...
The parameters and return values of this command are the same as those of _cat/indices of open-source Elasticsearch. Archiving a Frozen Index NOTE: Archive storage is available only for Elasticsearch 7.10.2 clusters whose image version is 24.3.0.C001 or later. Only indexes that are frozen ...
