To decide which server configurations to index, the search service reads the search configuration XML file installed under Program Files\Micro Focus\<StarTeam Server Version>\Search\config\starteam-search-configs.xml
Once search is enabled on a server configuration, a new search configuration is created in the starteam-search-configs.xml file.
To exclude sandbox views, open the starteam-search-configs.xml file and update <option name="ExcludeSandboxViews" value="1"/>. 1 enables exclusion. 0 disables exclusion.
A template for the configuration file is available under the same folder.
