Indexing Your Documents

Scheduling Regular Maintenance

You can schedule collection maintenance at regular intervals. You can set up
separate maintenance schedules for optimizing and reindexing. 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. 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 is to set up a pair of regularly scheduled
reindex and update operations to clean out deleted entries an to add entries for
new documents matching your collection criteria.
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.
You can reindex a collection, which locates each file that 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 add entries for new documents but cleans up the
collection by removing entries to files that have been deleted.
You can update a collection, by entering new indexing criteria for the
collection, say *.html, which adds any new documents that match the criteria.
