I'm putting my findings here, as seems to me related. In a mid size
corpora I've found the following mistery:
1) +SZIDO:"jan 1" -- 92 hits
2) +SZIDO:"jan 1" +TYPE:ER-CIKK -- 433 hits
3) +SZIDO:"jan 1" +TYPE:ER-CIKK NONSENSE:nonsense -- 92 hits
2) is obviously a nonsense. The NONSENSE field in the 3rd query
does not exists. Altough I do not understand what's happening,
and couldn't produce a revealing test case, I've found that if
I switch off the ConjunctionScorer optimization (the same way
as the 3rd query switched it off) by inserting
///////////////////////////////////////////////////////////////////
allRequired = false;
///////////////////////////////////////////////////////////////////
if (allRequired && noneBoolean) { // ConjunctionScorer is okay
this bug disappears. Also, found that (at least for me) only the
PhraseQuery produces this result. If I change the 2nd query with
2A) +SZIDO:(+jan +1) +TYPE:ER-CIKK
I gain the (good) 92 hits result. I'm almost sure that there is something
wrong with the document order and skipto what is specific to the
PhraseQuery.
