A word from text
my $term = Plucene::Index::Term->new({ field => $field_name, text => $text, }); # with two Plucene::Index::Term objects you can do: if ($term1->eq($term2)) { ... } # etc
A Term represents a word from text, and is the unit of search. It is composed of two elements, the text of the word, as a string, and the name of the field that the text occured in, as a string.
Note that terms may represent more than words from text fields, but also things like dates, email addresses, urls, etc.
Exactly what you would think they are.
