About re-indexing
You will need to re-index your Bamboo build results data whenever you perform a data import. Re-indexing your data can also be helpful if your reports appear to be out-of-sync with your data. Bamboo will not be accessible while the re-indexing process is running. This may take a few minutes to complete (see System Information for an estimate of how long it will take).
