Not all archives are monitored equally well by PhilArchive. For your archive content to be reliably indexed, we recommend that you use OAI sets to organize its contents. You should make sure that you have a set for philosophy material and tell PhilArchive to index just that set when configuring your archive.You shouldn't try to make PhilArchive index content that is not relevant to the site, because this will lead to your archive being avoided by the indexer.
