[Gramps-users] Birth Date and/or Death Date filters in the People view

[b4m <bes...@gm...>]

A question please, regarding the use of the Birth Date and/or Death Date
filters in the People view.

If I enter a Birth date filter of "bef 1812" the search still returns all
dates where the value is "about YYYY", "about YYYY-MM-DD" etc., even if
these dates are much later than the filter year selected.

Is it the case that the use of the string "about" or "abt" in a Gramps date
field nullifies any selection criteria by date?

If I were to omit the term "about" when recording a date about which I have
a low level of confidence that would imply a spurious level of accuracy,
but if I use the term "about" it seems to make filtering or searching very
hard.

Other than leaving ot the string "about" or "abt" when I record date
information is there currently any way to express a date or any syntax I
can use in a search so that a Birth date filter will return results within
a sensible range around an "about" date?

Thanks.
