--- Comment #7 from David Cook <dcook at prosentient.com.au> ---
As for bug 14861, you'll notice the CCL qualifiers are
"acqdate,st-date-normalized". That st-date-normalized gives it a structure
attribute of "date".
If we follow the spec for "date", we find:
The day, month, year and time when a
(normalized) transaction or event takes place. The
date search term structure is as defined
for Generalized Time in ASN.1 (ISO 8824)
except that the only mandatory portion of
the string is the four-digit representation
of the year.

Some Googling suggests ISO 8824 might use the following format:
Format: YYYY[MM[DD[HHMM[SS[.S[S[S[S]]]]]]]][+/-ZZZZ]^
Of course, I don't know how ICU and CHR normalization rules factor in with the
"2011-09-01 - 2011-09-30" search string...
