Multi-Index Operations and Aliases

• Entire cluster search:

  curl 'localhost:9200/_search?q=id:1'
  

• Multiple indices search:

  curl 'localhost:9200/index1,index2/_search?q=id:1'
  

• Wildcard search:

  curl 'localhost:9200/index*/_search?q=id:*'
  

• Index alias - create an alias for index or for group of indexes:

  curl -XPOST 'http://localhost:9200/_aliases' -d '
  {
    "actions" : [
        { "add" : { "index" : "test1", "alias" : "alias1" } },
        { "add" : { "index" : "test2", "alias" : "alias1" } }
    ]
  }'
  

• Why bother? Logical data partitioning, archiving by index, access control...
