To get started with JQL Search Extensions for Jira Data Center (JSE):

1. Install the latest version of JQL Search Extensions for Jira Data Center.
2. In Jira, go to [Advanced Search](https://appfire.atlassian.net/wiki/spaces/JQLSEARCH/pages/604209431/Get+started+with+JQL+Search+Extensions+for+Jira+Data+Center#Enter-a-query-in-Advanced-search-in-Jira).
3. Start typing the JQL query: `issue in`.
4. Jira autocompletes your query, and you can choose the required function. For example, you can run the query `issue in linksCountGreaterThan(2)`.

See the full list of JQL functions in the JQL functions [reference documentation](https://appfire.atlassian.net/l/cp/CDfkTFku).
