Configuring full-text indexing

Meridian Explorer uses the full-text indexing feature of the database where the repository is stored to index the text of documents, memo properties, and file properties. The indexes are generated from the files when documents are imported into the repository. As new revisions of the documents are imported into the repository, the indexes should be updated to contain the latest content.

Note    The performance of full-text searches in repositories hosted in Oracle can be improved by creating a setting named MRE3203 and setting it to true in the WebConfigDto.dat file on the Meridian Enterprise Server computer as described in Troubleshooting full-text indexing.

For information about managing the property indexes for general, non-content searches, see Configuring item names and indexing.

To configure full-text indexing:

1. In Meridian Enterprise Server Administration Console, in the Repositories group, click Repositories. The Repositories page appears and lists the existing Meridian Explorer repositories and Meridian Enterprise vaults.
2. Double-click the name of the repository that you want to configure. The Overview page for the repository appears.
3. In the menu, click MANAGEMENT TOOLS. The management tools for the selected repository appear.
4. In the FULL-TEXT INDEX group, for the Build full text index item, click EDIT. The FULL-TEXT INDEX SETTINGS dialog box appears.
5. Click options or type values using the descriptions in the following table.
6. Click UPDATE. The specified values appear in the FULL-TEXT INDEX group.

Full-text indexing options

Option	Description
Regenerate items that failed before	By default, if full-text indexing fails for a document, that document will be skipped during the next index update. Enable this option to retry indexing the document during each update.
Excluded file extensions	Type a semicolon-delimited list of file extensions to exclude from full-text indexing. These should be file extensions for which IFilters are not installed on the server. By default, all file extensions that are registered for an installed IFilter are included. To view the list of installed IFilters, see Viewing the full-text filters.
Timeout in seconds	The amount of time in seconds to wait for index updates to complete before an error is entered in the event logs and processing is stopped. Note    The indexing process can stop responding if it encounters a problem in the source file.

To generate the full-text indexes immediately:

• In the FULL-TEXT INDEX group, for the Run or schedule this task item, click RUN. A background task is started and you can continue working.

To schedule full-text indexing:

1. In the FULL-TEXT INDEX group, for the Run or schedule this task item, click SCHEDULE. The SCHEDULE dialog box appears. This dialog box requires the same input as the Windows Task Scheduler.
2. Configure the scheduled task to run when you require and then click SCHEDULE.The task is modified and will run on the configured schedule.
