Solr Index-Time Document Boosts not working

I can't find any solid documentation on using index-time document boosts, aside from how set the boost and that omitNorms needs to be set to false on the field types you're querying. I'm really at a loss as to what's happening here. (again -- SIMPLE query, no filters or anything else)

Assuming I do a simple search for title:scissor or even just "scissor", I get back 5 results. If I set a boost of anything between 1.1-1000 on any of these results besides the first result, I would expect this result to have a higher score in the next search.

What's happening to me, however, is that these boosted results are coming back with LOWER scores than before I boosted them, and if I try to boost or negatively boost (0.1-0.9) the top result it NEVER changes position).

For example below, I added a boost of "5" to the fifth result (this is pre-boost):

"explain": {   "File #1": "\n6.312951 = weight(title:scissor in 495641) [ClassicSimilarity], result of:\n  6.312951 = fieldWeight in 495641, product of:\n    1.0 = tf(freq=1.0), with freq of:\n      1.0 = termFreq=1.0\n    12.625902 = idf(docFreq=10, maxDocs=1231567)\n    0.5 = fieldNorm(doc=495641)\n",   "File #2": "\n5.5238323 = weight(title:scissor in 984389) [ClassicSimilarity], result of:\n  5.5238323 = fieldWeight in 984389, product of:\n    1.0 = tf(freq=1.0), with freq of:\n      1.0 = termFreq=1.0\n    12.625902 = idf(docFreq=10, maxDocs=1231567)\n    0.4375 = fieldNorm(doc=984389)\n",   "File #3": "\n5.5238323 = weight(title:scissor in 1098172) [ClassicSimilarity], result of:\n  5.5238323 = fieldWeight in 1098172, product of:\n    1.0 = tf(freq=1.0), with freq of:\n      1.0 = termFreq=1.0\n    12.625902 = idf(docFreq=10, maxDocs=1231567)\n    0.4375 = fieldNorm(doc=1098172)\n",   "File #4": "\n4.7347136 = weight(title:scissor in 901186) [ClassicSimilarity], result of:\n  4.7347136 = fieldWeight in 901186, product of:\n    1.0 = tf(freq=1.0), with freq of:\n      1.0 = termFreq=1.0\n    12.625902 = idf(docFreq=10, maxDocs=1231567)\n    0.375 = fieldNorm(doc=901186)\n",   "File #5": "\n4.7347136 = weight(title:scissor in 1037808) [ClassicSimilarity], result of:\n  4.7347136 = fieldWeight in 1037808, product of:\n    1.0 = tf(freq=1.0), with freq of:\n      1.0 = termFreq=1.0\n    12.625902 = idf(docFreq=10, maxDocs=1231567)\n    0.375 = fieldNorm(doc=1037808)\n",   "File #6": "\n4.7347136 = weight(title:scissor in 1044468) [ClassicSimilarity], result of:\n  4.7347136 = fieldWeight in 1044468, product of:\n    1.0 = tf(freq=1.0), with freq of:\n      1.0 = termFreq=1.0\n    12.625902 = idf(docFreq=10, maxDocs=1231567)\n    0.375 = fieldNorm(doc=1044468)\n",   "File #7": "\n4.4639306 = weight(title:scissor in 972468) [ClassicSimilarity], result of:\n  4.4639306 = fieldWeight in 972468, product of:\n    1.4142135 = tf(freq=2.0), with freq of:\n      2.0 = termFreq=2.0\n    12.625902 = idf(docFreq=10, maxDocs=1231567)\n    0.25 = fieldNorm(doc=972468)\n",   "File #8": "\n3.9455943 = weight(title:scissor in 896318) [ClassicSimilarity], result of:\n  3.9455943 = fieldWeight in 896318, product of:\n    1.0 = tf(freq=1.0), with freq of:\n      1.0 = termFreq=1.0\n    12.625902 = idf(docFreq=10, maxDocs=1231567)\n    0.3125 = fieldNorm(doc=896318)\n",   "File #9": "\n3.9455943 = weight(title:scissor in 1037733) [ClassicSimilarity], result of:\n  3.9455943 = fieldWeight in 1037733, product of:\n    1.0 = tf(freq=1.0), with freq of:\n      1.0 = termFreq=1.0\n    12.625902 = idf(docFreq=10, maxDocs=1231567)\n    0.3125 = fieldNorm(doc=1037733)\n",   "File #10": "\n3.1564755 = weight(title:scissor in 1045578) [ClassicSimilarity], result of:\n  3.1564755 = fieldWeight in 1045578, product of:\n    1.0 = tf(freq=1.0), with freq of:\n      1.0 = termFreq=1.0\n    12.625902 = idf(docFreq=10, maxDocs=1231567)\n    0.25 = fieldNorm(doc=1045578)\n" }, 

And now the fifth result has become the sixth result:

Specifically, the before/after of the result in question:

"File #5": "\n4.7347136 = weight(title:scissor in 1037808) [ClassicSimilarity], result of:\n  4.7347136 = fieldWeight in 1037808, product of:\n    1.0 = tf(freq=1.0), with freq of:\n      1.0 = termFreq=1.0\n    12.625902 = idf(docFreq=10, maxDocs=1231567)\n    0.375 = fieldNorm(doc=1037808)\n",  "File #5": "\n4.7020845 = weight(title:scissor in 0) [ClassicSimilarity], result of:\n  4.7020845 = fieldWeight in 0, product of:\n    1.0 = tf(freq=1.0), with freq of:\n      1.0 = termFreq=1.0\n    12.538892 = idf(docFreq=11, maxDocs=1231568)\n    0.375 = fieldNorm(doc=0)\n", 

Any assistance in explaining to me what's happening here would be greatly appreciated. I'm at a loss as to why this is happening.
