-/**
- * A {@link SlopQueryNode} represents phrase query with a slop.
- * 
- * From Lucene FAQ: Is there a way to use a proximity operator (like near or
- * within) with Lucene? There is a variable called slop that allows you to
- * perform NEAR/WITHIN-like queries. By default, slop is set to 0 so that only
- * exact phrases will match. When using TextParser you can use this syntax to
- * specify the slop: "doug cutting"~2 will find documents that contain
- * "doug cutting" as well as ones that contain "cutting doug".
