If you want to limit number of shards or indices there is no other option than use _reindex to merge few indices into one. This can take a while depending on the number and size of indices you have.

Indices is the plural of index. If you have more than one index you call them indices. http://www.thefreedictionary.com/index.

3 Mar 2016 ElasticSearch is schema less, and uses JSON instead of… to create an index, insert data into it and then retrieve data from elasticsearch.

Index APIs are used to manage individual indices, index settings, aliases, mappings, and index templates. Listing All Indexes in Elasticsearch Cluster Published on December 10, 2015 by Bo Andersen If you want to list all of the indexes within an Elasticsearch cluster, then there are a few ways to do just that. The Create Index API is used to manually create an index in Elasticsearch. All documents in Elasticsearch are stored inside of one index or another. The most basic command is the following: (Optional, string) Comma-separated list or wildcard expression of index names used to limit the request. To retrieve statistics for all indices, use a value of _all or * or omit this parameter.

Hi, I have just started exploring Elastic Search. I have a requirement similar to below thread I want to store the data specific to brands for efficient search. I have around 4k brands and each brand has around 10k files. Initially I was thinking of creating one index per brand and store data. But looking at above link it is not efficient. Second option was to create different index type for When I try to change my visualizations in Kibana I get the following message: Visualization Editor: blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];: [cluster_block_exception] blocked by: [FORBIDDEN/12/index read-only / allow delete (api)]; So somehow my indices got locked. I allready tried out the proposed solution in the following post, which unfortunately doesn't work for me By not limiting our search to a particular index or type, we have searched across all documents in the cluster. Elasticsearch forwarded the search request in parallel to a primary or replica of every shard in the cluster.
