Search like keyword mongodb

I got a problem when trying to create a search function in MongoDB, some articles that I read tell find just using a string, not a variable. I need to create a function that can search LIKE in SQL.

  async findAllLike(parameter, limit) {
    const ctx = "mongodb-findManyLike";
    const dbName = await this.getDatabase();
    const result = await mongoConnection.getConnection(this.config);
    if (result.err) {
      logger.log(ctx, result.err.message, "Error mongodb connection");
      return result;
    }
    try {
      const cacheConnection = result.data.db;
      const connection = cacheConnection.db(dbName);
      const db = connection.collection(this.collectionName);
      const recordset = await db
        .find({ title: { $search: parameter } })
        .sort({ createdAt: -1 })
        .limit(limit)
        .toArray();
      if (validate.isEmpty(recordset)) {
        return wrapper.error("Data Not Found , Please Try Another Input");
      }
      return wrapper.data(recordset);
    } catch (err) {
      logger.log(ctx, err.message, "Error find data in mongodb");
      return wrapper.error(`Error Find Many Mongo ${err.message}`);
    }
  }
