Fields
|
|
------
|
|
|
|
Fields are groups of words which each represent a significant part of the whole name. This concept
|
|
is sifnificant in music file names, where we often have names like "My Artist - a very long title
|
|
with many many words".
|
|
|
|
This title has 10 words. If you run as scan with a bit of tolerance, let's say 90%, you'll be able
|
|
to find a dupe that has only one "many" in the song title. However, you would also get false
|
|
duplicates from a title like "My Giraffe - a very long title with many many words", which is of
|
|
course a very different song and it doesn't make sense to match them.
|
|
|
|
When matching by fields, each field (separated by "-") is considered as a separate string to match
|
|
independently. After all fields are matched, the lowest result is kept. In the "Giraffe" example we
|
|
gave, the result would be 50% instead of 90% in normal mode.
