------------------------------------
Summary: Loosen up DirectSpellChecker's minPrefix requirements
Key: LUCENE-4500
URL: https://issues.apache.org/jira/browse/LUCENE-4500
Project: Lucene - Core
Issue Type: Improvement
Affects Versions: 4.0
Reporter: Erik Hatcher
Priority: Minor
DirectSpellChecker currently mandates a minPrefix of 1 when editDistance=2.
This prohibits a query of "nusglasses" from matching the indexed "sunglasses"
term.
Granted, there can be performance issues with using a minPrefix of 0, but it's
a risk that a user should be allowed to take if needed.
