/**
* Builder class which allows to instantiate the different field descriptors.
* Any field, apart from being able to be multi-valued or single-valued, has 7 basic modifiers:
* - stored: whether the content of the field is stored on the index or not.
* - indexed: Whether the field is indexed or not.
* - fulltext: whether the field is used for fulltext search or not.
* - language: the language of the content field.
* - boost: boosting value to give more or less relevance to the field.
* - facet: whether the field can be used for faceting or not.
* - suggest: whether the field can be used for suggestions or not.
*
* The field can also have metadata properties defined by the user.
* By default a new field is stored and indexed with no language and a boost of 1 (no boosting).
