New description:
Example:
{{{
year:2008-02->2008-06
}}}
works ok.
However
{{{
year:2ai
}}}
yields the same results as
{{{
year:2008-02->2009
}}}
For the moment I suggest working around by splitting your date search in
twain (range to end of year, range from beginning of next). But this
should be repaired.

Comment:
Note that the `year` index is composed of two MARC fields, `773__y`
and `269__c`. The publication year stored in the former is four
digits only, so if you search for values of up to `2009-02`, you will
get all `2009` publications matched via 773 (since `2009 < 2009-NN`).
So I think that what you observe is a by-product of the fact that we
store sometimes four digits sometimes more digits inside the same
index.
If you would like to search in 269 only, then please try queries like:
{{{
269__c:2008-02->2009-02
269__c:2008-02->2009-06
}}}
where I think everything works as expected.
If you would like to search in some other way, then please provide
more details.
