When I run this query I get 64 results, as expected:
project = PGE and issuetype = Story and "Epic Link" = PGE-1574 and Sprint = 182
When I run this query, which adds the issueLinkType clause, I get 0 results, though I was expecting 64 results.
project = PGE and issuetype = Story and "Epic Link" = PGE-1574 and Sprint = 182 and issueLinkType != "is blocked by"
This clause is taken from the <a href="https://support.atlassian.com/jira-software-cloud/docs/advanced-search-reference-jql-fields/" target="_blank" rel="noopener nofollow noreferrer">JQL fields documentation</a>.
