Multiple Indices
editMultiple Indices
editMost APIs that refer to an index parameter support execution across multiple indices,
using simple test1,test2,test3 notation (or _all for all indices). It also
support wildcards, for example: test* or *test or te*t or *test*, and the
ability to "exclude" (-), for example: test*,-test3.
All multi indices API support the following url query string parameters:
-
ignore_unavailable -
Controls whether to ignore if any specified indices are unavailable, this
includes indices that don’t exist or closed indices. Either
trueorfalsecan be specified. -
allow_no_indices -
Controls whether to fail if a wildcard indices expressions results into no
concrete indices. Either
trueorfalsecan be specified. For example if the wildcard expressionfoo*is specified and no indices are available that start withfoothen depending on this setting the request will fail. This setting is also applicable when_all,*or no index has been specified. This settings also applies for aliases, in case an alias points to a closed index. -
expand_wildcards -
Controls to what kind of concrete indices wildcard indices expression expand to. If
openis specified then the wildcard expression is expanded to only open indices and ifclosedis specified then the wildcard expression is expanded only to closed indices. Also both values (open,closed) can be specified to expand to all indices.If
noneis specified then wildcard expansion will be disabled and ifallis specified, wildcard expressions will expand to all indices (this is equivalent to specifyingopen,closed).
The defaults settings for the above parameters depend on the api being used.
Single index APIs such as the Document APIs and the
single-index alias APIs do not support multiple indices.
