Issue Summary

When migrating repositories from one DC instance to another using the Export and import projects and repositories method, the imported repositories are not searchable

This is reproducible on Data Center: (yes) 

Steps to Reproduce

1. Export a project using Exporting
2. Import a project to another instance using Importing -
3. Search for content in the main branch of one of the imported repositories

Expected Results

After the import, search indexing is triggered for the imported repositories, and the content is searchable

Actual Results

While the index for searching the project/repository name is indeed created ("bitbucket-project" and "bitbucket-repository", the following index is not: "bitbucket-state-index", and the "bitbucket-search" index is not populated with content from those repositories.

The repositories are not searchable.

There is no exception thrown in the atlassian-bitbucket.log file however the IndexFilesResult lines are missing in debug, and only IndexResult is shown after migration

2024-06-20 14:58:17,908 DEBUG [search-indexing:thread-1]  c.a.b.i.s.i.e.DefaultIndexEventWorker Indexing - Results for project TEST (id: 22) is: IndexResult{created=true, id='22', sequenceNumber='SequenceNumber[sequenceNumber=14, primaryTerm=9]', version=1}

When querying the index state using the Search server API

curl -u <SEARCH_USERNAME>:<SEARCH_PASSWORD> -X GET <search-server>:9200/bitbucket-index-state/_doc/<REPO_ID>

the index is not found

{"_index":"bitbucket-index-state","_type":"_doc","_id":"<REPO_ID>","found":false}

Workaround

After the projects/repositories are migrated issue the following API statement to trigger reindexing - only the newly imported repositories will be indexed

curl -u username:password -X POST -v -H 'Content-Type: application/json' -H 'Accept: application/json' <BITBUCKET_URL>/rest/indexing/latest/sync
