 * 'QueryBuilder' Is a Typescript class that provides the ability to build a query string using the Lucene syntax in a more readable way.

 *  const qb = new QueryBuilder();
 *  const query = qb
 *          .field('contentType')
 *          .equals('Blog')
 *          .field('conhost')
 *          .equals('my-super-cool-site')
 *          .build(); // Output: `+contentType:Blog +conhost:my-super-cool-site"`
 * ```
 *
 * @example
 * ```ts
 *  const qb = new QueryBuilder();
 *  const query = qb
 *          .field('contentType')
 *          .equals('Blog')
 *          .field('title')
