Set Language Specific Rules for String Comparison

Important

This feature is unavailable in MongoDB Compass Community Edition.

Use the Collation query bar option to specify language-specific rules for string comparison, such as rules for lettercase and accent marks.

Set Collation

  1. In the Query Bar, click Options.

  2. Enter the locale field in the collation document to specify the ICU Locale code for the desired language in the Collation field.

    Example

    To use the pinyin variant of the Chinese collation, use the following collation document:

    { "locale" : "zh@collation=pinyin" }
    

    As you type, the Find button is disabled and the Collation label turns red until a valid query is entered.

  3. Click Find to run the query and view the updated results.

Clear the Query

To clear the query bar and the results of the query, click Reset.
