set the following values:

.. list-table::
   :header-rows: 1
   :widths: 20 80
   :class: tight-table
 
   * - Parameter
     - Description
   * - *Lucene Unlimited Matches*
     - If true then queries using the Lucene text index will not use an upper boundary (10000) of matches. Activating this will return more complete results but may lead to bad worst-case performance. This setting applies to EDG editors and not Search the EDG
   * - *Use Lucene WhitespaceAnalyzer*
     - Changes the Lucene index analyzer (currently used for the Text Indices/GraphQL-based and Seach the EDG queries only). The default StandardAnalyzer drops characters, such as slash ("/") and hyphen ("–"), while the WhitespaceAnalyzer preserves them. Note: Requires a server restart and re-indexing to take effect.
   * - *Search the EDG Globally Enabled*
     - If true, all asset collections are included in Search the EDG. Note: Requires a server restart to take effect.
