Section 3.5, “Reindexing” describes how to re-index search indices in general. You can re-index everything from scratch as described in Section 3.5.4, “Reindexing Content Feeder and CAE Feeder Indices from Scratch”, or only parts of the index as described in Section 3.5.2, “Partial Reindexing of Content Feeder Indices”. The latter section also describes how to re-index only some aspects of contents, for example content issues.
