As of now, this causes a problem with "Farming for Dummies". The "for" means the item name won't be registered correctly. Use of more robust regular expressions can fix this.

For example, the bank calculator uses it properly: https://github.com/symt/BazaarNotifier/blob/beta/src/main/java/dev/meyi/bn/modules/calc/BankCalculator.java

Every single split call that is used to parse out the amount, price, name, etc. of an order should be replaced with regex

This will be done with 1.8.0
