Hoss Man updated SOLR-3981:
---------------------------
Attachment: SOLR-3981.patch
bq. i want to work on a test that actually indexes a doc and inspects the
encoded norms just to be certain i'm not missing something.
Updated patch adds this to the test -- kludgy to reach this deep into the
lucene code in the solr test, but do-able.
Unfortunately the test fails because the decoded norms from the index wind up
being way _lower_ then the expected values.
At first i thought it was just because i forgot to factor in the term length in
my expected norm, but even taking that into account the numbers are still way
off. i'm guessing either i don't understand something about the new 4.0 APIs
for getting the DocValues/Norms, or i've got some trivially silly bug that i'm
blind too because i've been staring at it too long.
I'd appreciate a second set of eyes.

> {quote}
> While boosting of multi-value fields is handled correctly in Solr 4.0.0,
> boosting for copyFields are not. A sample document:
> {code}
> <add><doc boost="10.0">
> <field name="id">Insane score Example. Score = 10E9 </field>
> <field name="name">Document boost broken for copyFields</field>
> <field name="manu" >video ThomasEgense and Toke Eskildsen</field>
> <field name="manu_id_s">Test</field>
> <field name="cat">bug</field>
> <field name="features">something else</field>
> <field name="keywords">bug</field>
> <field name="content">bug</field>
> </doc></add>
> {code}
> The fields name, manu, cat, features, keywords and content gets copied to
> text and a search for thomasegense matches the text-field with query
> explanation
> {code}
> 70384.67 = (MATCH) weight(text:thomasegense in 0) [DefaultSimilarity], result
> of:
> 70384.67 = fieldWeight in 0, product of:
> 1.0 = tf(freq=1.0), with freq of:
> 1.0 = termFreq=1.0
> 0.30685282 = idf(docFreq=1, maxDocs=1)
> 229376.0 = fieldNorm(doc=0)
> {code}
> If the two last fields keywords and content are removed from the sample
> document, the score is reduced by a factor 100 (docBoost^2).
> {quote}
> (This is a continuation of some of the problems caused by the changes made
> when the concept of docBoost was eliminated from the underly IndexWRiter
> code, and overlooked due to the lack of testing of docBoosts at the solr
> level - SOLR-3885))
