Fruitful variants, Enhanced

• Short Description: Retrieve or generate all fruitful variants for the input.
  
  
• Full Description:

  This flow component is intended to improve performance on generating fruitful variants. It utilizes the flow component of -f:v first to retrieve fruitful variants from a pre-computed database. If no records are found, use the flow -f:G to generate fruitful variants.

  There is a difference on the result between this flow and -f:G flow. This is because -f:v flow is case insensitive.

  The history notation and distance score are shown below:

  Operation	Notation	Distance score
  No Operations	n	0
  Spelling Variant	s	0
  Inflectional Variant	i	1
  Synonym	y	2
  Acronym/Abbreviation	A	2
  Expansion	a	2
  Derivational Variant	d	3

  Only suffix derivations are used to generate fruitful variants after 2018.

  The -m option shows detail mutate information includes flow history, distance score, and tag information. The tag information is represented by a long value by combining tag bit values. Currently, two bits are defined as listed in following table:

  Bit	Value	Tag
  0	1	Noun/Adj only in recursive derivation
  1	2	Unique acronyms/expansion

  Please refer to Tag class for details.
  
  

• Difference:

  The data in the Java version is much more thorough.

• Implementation Logic:
  1. Utilize -f:v to retrieve all variants from a database table.
  2. If no record found, utilize -f:G to generate all variants.
