file1:
>word1
>word2
>word3
the identifier is '>', the 'word..' can be whatever.
file2:
Query= wordx
Query= wordy
Query= wordz
the identifier is 'Query= ', the 'word..' is not identical to the one in file1, but comes in the right order (word1~wordx).
the result:
>wordx
>wordy
>wordz

plucene::search::query
Plucene::Search::Query(3pm) User Contributed Perl Documentation Plucene::Search::Query(3pm)
NAME
Plucene::Search::Query - base class for queries
SYNOPSIS
my $s_query = Plucene::Search::Query::Subclass->new({
boost => $boost_factor});
my $scorer = $s_query->scorer($query, $searcher, $reader);
DESCRIPTION
This is an abstract base class for queries.
A query is a specification of the content an properties of the desired documents. Every search is done by matching a query against the
document index and locating the ones that match the query.
The simplest query specifies a single term (or word) that is to be matched against a single field (e.g. 'author') of each of the documents
in the index. This kind of query matches any document that contains the term in the specified field.
A more complex queries may contain nested queries with 'and', 'or', 'not' or 'phrase' relations. Queries may also contains specification of
which document fields to match against the various parts of the query (.e.g. 'authors' and 'title') and hints that may effects the ranking
of the matched documents ('boost' factor).
METHODS
new
my $s_query = Plucene::Search::Query::Subclass->new({
boost => $boost_factor});
