docs: Create a tinyDB Query object that looks for items that confirms the correspondent operator
      from `operators` for each `field_names` field values from `data`.
  
      Parameters
      ----------
      data: dict
          The data sample
  
      field_names: str or list of str
          The name of the fields in `data` that will be used for the query.
  
      operators: str or list of str
          A list of comparison operations for each field value in `field_names`.
          If this is a str, will use the same operator for all `field_names`.
          If you want different operators for each field, remember to use an OrderedDict for `data`.
          Check TinyDB.Query class for possible choices.
  
      Returns
      -------
      query: tinydb.database.Query
