// GetForeignIndex presents the foreign index, which could be misused:
// For example, if there are 2 Gitea sites: site-A exports a dataset, then site-B imports it:
// * if site-A exports files by using its LocalIndex
// * from site-A's view, LocalIndex is site-A's IssueIndex while ForeignIndex is site-B's IssueIndex
// * but from site-B's view, LocalIndex is site-B's IssueIndex while ForeignIndex is site-A's IssueIndex
//
// So the exporting/importing must be paired, but the meaning of them looks confusing then:
// * either site-A and site-B both use LocalIndex during dumping/restoring
// * or site-A and site-B both use ForeignIndex
