=head1 NAME
Plucene::Analysis::Analyzer - base class for Analyzers
=head1 SYNOPSIS
my $analyzer = Plucene::Analysis::Analyzer::Subclass->new;
=head1 DESCRIPTION
This is an abstract base class of Analyzers.
An Analyzer builds TokenStreams, which analyze text. It thus represents
a policy for extracting index terms from text.
Typical implementations first build a Tokenizer, which breaks the stream
of characters from the Reader into raw Tokens. One or more TokenFilters
may then be applied to the output of the Tokenizer.
