Class SlopQueryNode
A 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".
