I tried commenting out the final OR term, and that excluded all records that
were out-of-language as expected. It's just the boost that doesn't seem to
work.
Exploring the explain is challenging because of its size, but there are NO
boosts recorded of the size I am using (10.0). Here's the basic structure of
the first result.
0.0 = (MATCH) sum of:
0.0 = (MATCH) sum of:
0.0 = (MATCH) weight(language:eng in 52867945), product of:
0.0 = queryWeight(language:eng), product of:
1.0 = idf(docFreq=23889670, maxDocs=59327671)
0.0 = queryNorm
1.0 = (MATCH) fieldWeight(language:eng in 52867945), product of:
1.0 = tf(termFreq(language:eng)=0)
1.0 = idf(docFreq=23889670, maxDocs=59327671)
1.0 = fieldNorm(field=language, doc=52867945)
0.0 = (MATCH) product of:

It looks like the PRODUCT_OF and SUM_OF, which represents the Boolean logic,
does not actually apply boost?

Then perhaps your language term doesn't actually match anything in the
index? (i.e. how is it analyzed?)
Next step would be to get score explanations (just add debugQuery=true
if you're using Solr, or see IndexSearcher.explain() if not).
