The benefit of indexing empty fields
In many archives metadata is only entered in certain fields, leaving most fields empty. When configured to index certain empty fields, Index Manager creates an entry in the index called xnoword for these fields, allowing users to search for empty fields using this string. This can be a good way to reduce the size of the index and, as a result, speed up searching in very large archives.
