Search Queries


The most basic query is composed of a value but can also contains a field and its value, in the form of field:value. When only specifying the value, all fields are tested against it.

A query can use any field, visible or not, to match a value, such as:

  • us-west-1
  • dc:us-west-1
  • subscriber:rabbitmq
  • subscription:linux
  • team:webops

Regular Expressions

Javascript’s RegExp object is used to retrieve the matches, thus the following special characters are available to use exclusively in the values of a query.

. - Matches any single character. For example, dc:a.stria matches the datacenter austria.

* - Matches the preceding character 0 or more times. For example, dc:can* matches the datacenters canada and vatican, but not cameroon.

+ - Matches the preceding character 1 or more times. For example, dc:ira+ matches the datacenters iran and iraq, but not ireland.

? - Matches the preceding character 0 or 1 time. For example, dc:oc?o matches the datacenter cameroon, but not morocco.

^ - Matches beginning of input. For example, dc:^por matches the datacenter portgual, but not singapore.

$ - Matches end of input. For example, dc:nea$ matches the datacenter guinea, but not guinea-bissau.

See the RegExp Object documentation for possible quantifiers.
