Hi, I have load balanced setup on Azure for my Umbraco site. Recently, functionality on slave site which uses internal index stopped returning results, (same functionality currently works on master site). For additional detail, there is three different load balanced instances with same codebase and setup and only one of them has this issue. Umbraco version used is 7.15.7 and indexes are configured using TempEnvDirectoryFactory.

Is there any way to force index update on a slave site? (preferably without any third party packages)
