[~jpountz], thanks for looking into this! Here's the old explain message:
{noformat}
202743.53 = <query>, product of:
587.6624 = sum of:
587.6624 = sum of:
587.6624 = sum of:
587.6624 = weight(username:barackobama in 0) [UserSimilarityProvider], result of:
587.6624 = score(doc=0,freq=1.0), product of:
33.93845 = queryWeight, product of:
1.96 = boost
17.315535 = idf, computed as log((docCount+1)/(docFreq+1)) + 1 from:
1.0 = docFreq
2.4365572E7 = docCount
1.0 = queryNorm
17.315535 = fieldWeight in 0, product of:
1.0 = tf(freq=1.0), with freq of:
1.0 = termFreq=1.0
17.315535 = idf, computed as log((docCount+1)/(docFreq+1)) + 1 from:
1.0 = docFreq
2.4365572E7 = docCount
1.0 = fieldNorm(doc=0)
345.0 = <query>
{noformat}
And here's the new one:

33.93783 = sum of:

17.31522 = fieldWeight in 0, product of:

1.0 = termFreq=1.0
17.31522 = idf, computed as log((docCount+1)/(docFreq+1)) + 1 from:
1.0 = docFreq
2.4357912E7 = docCount
1.0 = fieldNorm(doc=0)
345.0 = <query>
{noformat}
I'll take a look at the methods you mentioned.

I'll take a look at the IndexSearcher methods you mentioned and see if we missed anything in our code (it's possible we override some of this behavior, and did not make the appropriate changes).
