=head1 NAME
KinoSearch1::Search::TermQuery - match individual Terms
=head1 SYNOPSIS
my $term = KinoSearch1::Index::Term->new( $field, $term_text );
my $term_query = KinoSearch1::Search::TermQuery->new(
term => $term,
);
my $hits = $searcher->search( query => $term_query );
=head1 DESCRIPTION
TermQuery is a subclass of
L<KinoSearch1::Search::Query|KinoSearch1::Search::Query> for matching individual
L<Terms|KinoSearch1::Index::Term>. Note that since Term objects are associated
with one and only one field, so are TermQueries.
=head1 METHODS
=head2 new
my $term_query = KinoSearch1::Search::TermQuery->new(
term => $term,
);
Constructor. Takes hash-style parameters:
=over
=item *
B<term> - a L<KinoSearch1::Index::Term>.
