title: Jira Find Users API call querying an email address that includes a plus sign
body: <p>I am trying to use the Jira Rest API v3 call to <a href="https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-user-search/#api-rest-api-3-user-search-get" rel="nofollow noreferrer">Find users</a> to search for users by email address. The <code>GET</code> call works fine like with this syntax: <code>/rest/api/3/user/search?query={EmailAddress}</code>.</p>
  <p>However, in the case where the email address includes a <code>+</code> (plus) sign in the username portion of the email address, instead of searching on that email address, it performs a global search on <code>displayName</code> and <code>emailAddress</code> using the chars from both sides of the <code>+</code> sign.</p>
  <p>For example, searching for <code>john@example.com</code> returns just the user record with that email address. However, a search for <code>john+test@example.com</code> will return any user with an <code>emailAddress</code> or <code>displayName</code> that contains <code>john</code> <strong>OR</strong> contains <code>test</code> (and interestingly, does not limit the second one to be items containing <code>test@example.com</code>). It seems like adding the <code>+</code> is translated by the Jira API into an <code>OR</code> search for two different fragments of text.</p>
  <p>How can I search for users on the Jira Rest API having an email address that contains a <code>+</code> (plus) sign (a common, legal character) in the username of the email?</p>
