Text searches with negated terms in phrases don't match correctly

db.test.drop()

db.test.insert({words: "tyler dogs"})

db.test.ensureIndex({"words": "text"})

// expect no results, phrase match works

> db.test.runCommand('text', {search: "\"tyler cats\""})

{

	"queryDebugString" : "cat|tyler||||tyler cats||",

	"results" : [ ]

}

// expect no results, phrase match ignores cats!

> db.test.runCommand('text', {search: "\"tyler -cats\""})

{

	"queryDebugString" : "tyler||||||tyler -cats",

	"results" : [

		{

			"score" : 0.75,

			"obj" : {

				"_id" : ObjectId("51f2c3adf9477b8250ef438a"),
