FUZZY Matching

TapeMaster supports fuzzy pattern matching using the special filter prefix:

FUZZY:text:floor

• text the string you are searching for
• floor the minimum fuzzy score required for a match

A higher floor equals a stricter match, lower floor means a looser match. The fuzzy floor value is typically between 0 and 100.

Example set of Description values for Volumes in TapeMaster:

Production database weekly backup
Prod DB full backup
Prod data backup set
Production export dump
Development database backup
Weekly archive - finance system

Use a low floor value to allow broad matching, abbreviations, and partial similarity.

 FUZZY:production backup:40 

This will typically match:

Production database weekly backup
Prod DB full backup
Prod data backup set
PRD database BKP
Production export dump

This level is useful when Description fields are inconsistent or abbreviated.

Use a medium floor value for normal operational filtering. This reduces false positives while still allowing minor differences.

 FUZZY:production backup:70 

This will typically match:

Production database weekly backup
Prod DB full backup
Prod data backup set

This will typically exclude:

Production export dump
Development database backup
Weekly archive - finance system

This is recommended for most day-to-day filtering in TapeMaster.

Use a high floor value when the Description field is consistent and you require close similarity.

 FUZZY:production backup:90 

This will typically match:

Production backup
Production database backup

This will typically exclude:

Production database weekly backup
Prod DB full backup
Prod data backup set
PRD database BKP

This level is useful when you want to avoid incorrect or loosely related matches.
