multisearch
Description
The multisearch command is a generating command that runs multiple streaming searches at the same time. This command requires at least two subsearches and allows only streaming operations in each subsearch. Examples of streaming searches include searches with the following commands: search, eval, where, fields, and rex. For more information, see Types of commands in the Search Manual.
Syntax
| multisearch <subsearch1> <subsearch2> <subsearch3> ...
Required arguments
- <subsearch>
- Syntax: "["search <logical-expression>"]"
- Description: At least two streaming searches must be specified. See the search command for detailed information about the valid arguments for <logical-expression>.
- To learn more, see About subsearches in the Search Manual.
Usage
The multisearch command is an event-generating command. See Command types.
Generating commands use a leading pipe character and should be the first command in a search.
The multisearch command doesn't support peer selection
You can't exclude search peers from multisearch searches because the multisearch command connects to all peers by default. For example, the following multisearch search connects to the indexer called myServer even though it is excluded using NOT:
| multisearch
[ search index=_audit NOT splunk_server=myServer]
[ search index=_audit NOT splunk_server=myServer]
Subsearch processing and limitations
With the multisearch command, the events from each subsearch are interleaved. Therefore the multisearch command is not restricted by the subsearch limitations.
Unlike the append command, the multisearch command does not run the subsearch to completion first. The following subsearch example with the append command is not the same as using the multisearch command.
index=a | eval type = "foo" | append [search index=b | eval mytype = "bar"]
Examples
Example 1:
Search for events from both index a and b. Use the eval command to add different fields to each set of results.
| multisearch [search index=a | eval type = "foo"] [search index=b | eval mytype = "bar"]
