Indexing Your Documents
Maintaining a Collection
Periodically, you may want to maintain your collections. With normal usage,
these tasks may not be necessary, but if you do a great deal of indexing and
updating of collections, you may want to use some of these functions
occasionally. You can perform the following collection management tasks:
• Optimize collections —You can optimize a collection to improve
performance if you frequently add, delete, or update documents or
directories in your collections. An analogy is defragmenting your hard drive.
Optimizing is not done automatically, so you must manually optimize after
you reindex or update a collection. One situation when you might want to
optimize a collection is just before publishing it to another site or before
putting it onto a read-only CD-ROM.
• Reindex —You can reindex a collection, which locates each file that
already has an entry in the collection and reindexes its attributes and
contents, extracting the META-tagged attributes if that option was selected
when the files were originally indexed into the collection. This does not
return to the original criteria for creating the collection, say
*.html
, and
add any new documents that fit the original criteria. This option also
removes collection entries when the source documents have been deleted
and can no longer be found.
• Remove —You can remove a collection. This only removes the collection,
not the original source documents.
Note
Do not use your local file manager to remove collections, especially not the
web publishing collections. If by chance you do, when you try to execute a
search before restarting your server again, the search will fail even if it doesn’t
use the web publishing collection. Once you restart your server, a new web
publishing collection will be automatically created for you, so your search can
execute.
To perform any of the collection management tasks, use The Maintain
Collection Page in the Enterprise Server user interface.
