: What about at query time? If I index my Boolean and it has one of the
: variations of "t", "T" or "1", what should my query be to get a hit on
: "true"? q=MyBoolField:<what> ? What should the value of <what> be when I
: want to check if the field has a "true" and when I need to check if it has
: a "false"?
the string representations are parsed into the logical concepts -- it
doesn't matter if one doc was added with a value of "true" and another doc
was indexed with a value of "T" in the index they both have a true value.
likewise at query time it doesn't matter if you query for "true" or "T" -
they are both going to find all docs that have a true value, and querying
for "F" or "false" or "BOGUS" are going to find you all docs with a false
value.
where things get interesting is is when you deal with documents that do
not have a value in the field at all -- searching for something like
this...
q=-MyBoolField:true
...won't just return all the docs with a false value, it will also return
all docs w/o any value.
if you want to find all documents that don't have any value, you can
search for this...
q=-MyBoolField:*
note that the "*" is a query parser feature, so it causes the query parser
to do a "docs with value in this field" query w/o ever asking the
BoolField to "parse" the input string as a true/false value.
