Retrieve all fruitful variants from database
Generating the variants via the -f:G flow is a time consuming process. It was found to be useful to pre-compute all the variants of all terms from the Lexicon and have a quick look up into this pre-computed table.
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 |
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.
The data in the Java version is much more thorough.
