Index settings
Indexing is automatically configured in IBM Lotus Connections. However, when setting up indexing for your environment, you might need to perform additional configuration tasks.
For non-English deployments, enabling multilingual support for search is a mandatory post-installation step that needs to be performed before you start your Lotus Connections search server for the first time. Without multiple dictionary support, for languages other than English, search will only return results where there is an exact match between the search term and content term. Enabling multiple dictionaries ensures better quality search results when your user base is multilingual. For more information about enabling multilingual support, see Configuring dictionaries for search.
By default, the Lotus Connections user interface is displayed in the language identified in the locale settings of the Web browser being used. You can set it up to allow users to explicitly choose the language in which the product is displayed. For more information, see Enabling users to set a language preference. You can also perform the following optional post-installation configuration tasks relating to indexing:
- Configure J2C authentication for search
The connectionsAdmin J2C alias provides the credentials used when crawling Lotus Connections features. When you install Lotus Connections, the installation wizard automatically creates a search administrator role and configures J2C authentication for each feature. Indexing across all the features uses the connectionsAdmin J2C authentication alias. However, if you want to further secure the Lotus Connections environment, you can override this authentication alias on a feature-by-feature basis. For more information, see Configuring J2C authentication for search.
- Change the location of the search index
By default, the search index is stored in a path that is read from an IBM WebSphere Application Server variable. This variable can be updated to change the location of the search index. For example, customers using Linux or AIX might want to do this in order to move their index location to a that is mounted on a larger partition. For more information about moving the search index, see Changing the location of the search index.
- Configure dictionaries for search
The search feature provides globalization support by using different dictionaries for different languages. Each dictionary file must be enabled in the search configuration file before processing. By default, only the English language dictionary is enabled during installation.- Change the location of the search index
By default, the search index is stored in the search/index subdirectory of the IBM Lotus Connections data defined at install time, for example, on Linux, /opt/IBM/LotusConnections/Data/search/index. This location can be changed by editing the IBM WebSphere Application Server variable, SEARCH_INDEX_DIR.- Configure J2C authentication for search
When you install IBM Lotus Connections 2.5, the installation wizard automatically configures authentication and authorization for each feature. Crawling content for indexing occurs over an internal REST API interface, and the credentials used are retrieved from the connectionsAdmin J2C authentication alias that is configured during installation. The user ID from the credentials is also added to the search-admin J2EE role for each feature. To further secure the Lotus Connections environment, you can override this authentication alias on a feature-by-feature basis.
