How to use equals operator for atlas search in mongodb-driver-core Java library

I am using mongodb-driver-core 4.9.0, and noticed that the library does not offer many operators, like equals as mentioned in https://www.mongodb.com/docs/atlas/atlas-search/equals/

May I ask if I am missing anything here, or I would have to use SearchOperator.of(...) here? If so, I tried to pass in the equals Bson document, but it does not work in my query.

Looks forwards to your help! Thank you!

Hi Jeffrey, thank you for your reply!

I am trying to do something like:

  private static final String EQUAL_CLAUSE = """
      {
        "equals": {
          "path": "myFlag",
          "value": true
        }
      }
      """;

      filterOperators.add(SearchOperator.of(Document.parse(EQUAL_CLAUSE)));
      CompoundSearchOperator compoundSearchOperator = SearchOperator.compound().filter(filterOperators);
      if (!mustOperators.isEmpty()) {
        compoundSearchOperator = compoundSearchOperator.must(mustOperators);
      }
      if (!shouldOperators.isEmpty()) {
        compoundSearchOperator = compoundSearchOperator.should(shouldOperators);
      }
      aggregates.add(Aggregates.search(compoundSearchOperator));

However, it would yield with no results for me.

Found the issue in the index configuration. all good now.

Thank you!
