Indexing Collections with Verity Spider

Last updated 2/21/2012

Maintenance options

The Verity Spider maintenance options are:

-nooptimize

Prevents Verity Spider from optimizing the collection, thus reducing processing overhead during indexing. Use this

option sparingly, as it leaves the collection in less than optimum shape. The following are some examples of when you

might want to use this option:

• You want to manually perform custom optimization of the collection, using the mkvdk utility. By default, the Verity

Spider optimization mimics the mkvdk actions of maxmerge and vdbopt. For more information on the mkvdk

utility, see Verity Command-Line Indexing Reference and

“Using the mkvdk utility” on page 150.

• You are running multiple indexing jobs against a collection, and want to wait until they are all finished to optimize.

Generally, do not leave a collection unoptimized for too long, as search times can slow significantly.

In brief, optimizing a collection means creating a few large partitions, which can greatly reduce search times.

-purge

Deletes document tables and index files in the collection, and cleans up the collection's persistent store. The collection

is then fresh with its original style files, and is not deleted from the file system.

-repair

Specifies a failure-recovery mode for the collection, where the goal is to determine the causes of any errors, repair the

errors (if possible), and restart a collection.

Although the Verity indexing engine always leaves the collection in a consistent, usable state, and no data can be lost

or corrupted because of computer failures, it is possible for a process or event external to the Verity server to corrupt

one or more collections.

You can use the -repair option for constant failure-recovery operation, or you can run it selectively on collections

that failed.

Setting MIME types

You can use the -mimeinclude, -indmimeinclude, -mimeexclude, and -indmimeexclude MIME type criteria

options to include or exclude MIME types.

Syntax restrictions

Following are the restrictions when you specify MIME type criteria:

Using the wildcard character (*)

The asterisk (*) wildcard character does not operate as a regular expression for the value of the MIME type criteria.

Instead, you can only use it to replace the entire MIME type or MIME subtype.

For example, the following value is a valid substitute for text/html:

1 2 ... 147 148 149 150 151 152 153 154 155 156 157 ... 173 174
