Indexing Your Documents
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; you must manually optimize after you reindex or update a
collection. You might want to optimize a collection just before publishing it to
another site, or before putting it onto a read-only CD-ROM.
•
Reindex—You can reindex a collection. Each file that already has an entry in
the collection can be located and its attributes and contents reindexed.
META-tagged attributes will be extracted 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
documents that fit the original criteria. Collection entries are removed 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
To perform any of these collection management tasks, use The Maintain Collection
link in the Server Manager.
Scheduling Regular Maintenance
You can schedule collection maintenance at regular intervals, and you can set up
separate maintenance schedules for optimizing and reindexing. With normal
usage, these tasks may not be necessary, unless you index and update collections
frequently. For example, some very active web sites may require frequent
reindexing if new documents are added on a daily basis.
A common combination of tasks regularly schedules:
•
Cleaning out deleted entries with reindex and update operations
•
Adding entries for new documents matching your collection criteria.
•
Updating a collection by entering new indexing criteria for the collection

Do not use your local file manager to remove collections. When you try to
execute a search before restarting your server again, the search will fail.
