Configuring File Indexing for a DataFinder Instance

Last Modified: November 7, 2019

A DataFinder instance indexes the data in the search areas or in the SystemLink file service to be able to perform searches.

  1. In Data Indexing, click DataFinder Instances.
  2. Select an instance and click »Manage»Index.
  3. Configure the indexing process according to the following table.
    Setting Description
    Notify Analysis Automation instances about new or changed files (not available for the FileIndex instance) Notifies an Analysis Automation instance about new or changed data in the data source of a task. If you select a DataFinder instance in Analysis Automation as the data source for event-driven analysis automation procedures, Analysis Automation automatically enables this setting. If you disable this checkbox to reduce data traffic on the server, Analysis Automation can no longer perform the triggered tasks that use this DataFinder instance.
    Changes in the Search Areas (not available for the FileIndex instance) Updates the index when files are created or changed.

    The operating system notifies SystemLink about every new or changed file. Therefore, you should not use this setting if you expect a large amount of files or file changes.

    Indexing Schedule (not available for the FileIndex instance) Creates a data indexing schedule.
    Continuous Scan (not available for the FileIndex instance) Checks in the specified interval whether data has been added or deleted.
    Index Optimization Schedule Optimizes the index at the specified times.
    Timeout per File Maximum time in seconds the DataFinder instance takes to index a file.
    Use Optimized Background Processes Optimizes the background processes which the DataFinder instance applies to the index. For example, if you have deleted a search area or disabled a DataPlugin, the DataFinder instance only deletes the associated data from the index when computer resources are available.
    Number of Parallel Indexers Number of indexers which simultaneously index the data in the search areas. By default, a DataFinder instance uses four parallel indexers. You can use a maximum of eight parallel indexers. Using several parallel indexers can considerably impact the speed of your server.
    Index Adaptor Configures the index adaptor. Adaptors connect the DataFinder instance to a database, where they store the index. The connected databases may differ in performance and functionality.
  4. Click Apply in the highlighted area to accept the settings.
