Index and de-index programmatically
As we have seen in the JIRA architecture explained in Chapter 2, Understanding the Plugin Framework, searching in JIRA is based on Apache Lucene. The Lucene indexes are stored in the filesystem and are used as the basis for the search queries executed in JIRA. Whenever an issue is updated, more records are created or existing records are updated for that particular issue in the filesystem.
It is possible to programmatically index selected or all issues or de-index an issue. Also, we can switch indexing off or on selectively in our plugins if needed. An example where re-indexing is needed is when a custom post function updates a field on the issue. De-indexing might be needed if you want to hide the issue from search results, for example while archiving. In this recipe, we will see both of these examples.
How to do it…
Most of the indexing operations can be done with the help of IssueIndexManager. An instance of IssueIndexManager can be created either...
