Configuring Exact Keyword Matching on Search Engines

When a user queries content indexed data from a search interface, the Search Engine includes matches to the words in the query that have different word endings. You can configure the Search Engine to support exact matches to words using exact keyword matching.

About Exact Keyword Matching

By default, if a Compliance Search user performs a search using the query book, then the search results will include items that contain matches to book, books, and booking. If you only want to return exact matches, in this case only items that contain the exact word book, then you can configure exact matching on the Search Engine and use the dq prefix in the search query (dq:book).

Note: Only data that was content indexed by a Search Engine with exact keyword matching enabled will support searching using the dq: prefix. If you want to use dq: on data that was already content indexed, you must perform content indexing on the data again. For more information, see Re-pick a Job.


  1. From the CommCell Browser, go to Storage Resources > Search Engines.
  2. Right-click the Search Engine, and then click Properties.
  3. On the Server Config tab, configure exact matching as follows:
    • To enforce exact matching, select Exact keyword match support.
    • To match words with different word endings, clear Exact keyword match support.

      Note: This configuration applies to data that is content indexed using this Search Engine.

  4. Click OK.

    Services on the Search Engine nodes are restarted automatically.


You can now use the dq: prefix to perform exact keyword searching from search interfaces. For more information, see Compliance Search Advanced Search - Custom Query.
