KinoSearch1::Analysis::Stopalizer - suppress a "stoplist" of common words SYNOPSIS
my $stopalizer = KinoSearch1::Analysis::Stopalizer->new( language => 'fr', ); my $polyanalyzer = KinoSearch1::Analysis::PolyAnalyzer->new( analyzers => [ $lc_normalizer, $tokenizer, $stopalizer, $stemmer ], ); DESCRIPTION
A "stoplist" is collection of "stopwords": words which are common enough to be of little value when determining search results. For example, so many documents in English contain "the", "if", and "maybe" that it may improve both performance and relevance to block them. # before @token_texts = ('i', 'am', 'the', 'walrus'); # after @token_texts = ('', '', '', 'walrus'); CONSTRUCTOR
new my $stopalizer = KinoSearch1::Analysis::Stopalizer->new( language => 'de', ); # or... my $stopalizer = KinoSearch1::Analysis::Stopalizer->new( stoplist => \%stoplist, ); new() takes two possible parameters, "language" and "stoplist". If "stoplist" is supplied, it will be used, overriding the behavior indicated by the value of "language". o stoplist - must be a hashref, with stopwords as the keys of the hash and values set to 1. o language - must be the ISO code for a language. Loads a default stoplist supplied by Lingua::StopWords. SEE ALSO

KinoSearch1::Searcher(3pm) User Contributed Perl Documentation KinoSearch1::Searcher(3pm) NAME
KinoSearch1::Searcher - execute searches SYNOPSIS
my $analyzer = KinoSearch1::Analysis::PolyAnalyzer->new( language => 'en', ); my $searcher = KinoSearch1::Searcher->new( invindex => $invindex, analyzer => $analyzer, ); my $hits = $searcher->search( query => 'foo bar' ); DESCRIPTION
Use the Searcher class to perform queries against an invindex. METHODS
new my $searcher = KinoSearch1::Searcher->new( invindex => $invindex, analyzer => $analyzer, ); Constructor. Takes two labeled parameters, both of which are required. o invindex - can be either a path to an invindex, or a KinoSearch1::Store::InvIndex object. o analyzer - An object which subclasses KinoSearch1::Analysis::Analyer, such as a PolyAnalyzer. This must be identical to the Analyzer used at index-time, or the results won't match up. search my $hits = $searcher->search( query => $query, # required filter => $filter, # default: undef (no filtering) ); Process a search and return a Hits object. search() expects labeled hash-style parameters. o query - Can be either an object which subclasses KinoSearch1::Search::Query, or a query string. If it's a query string, it will be parsed using a QueryParser and a search will be performed against all indexed fields in the invindex. For more sophisticated searching, supply Query objects, such as TermQuery and BooleanQuery. o filter - Must be a KinoSearch1::Search::QueryFilter. Search results will be limited to only those documents which pass through the filter. Caching a Searcher When a Searcher is created, a small portion of the invindex is loaded into memory. For large document collections, this startup time may become noticeable, in which case reusing the searcher is likely to speed up your search application. Caching a Searcher is especially helpful when running a high-activity app under mod_perl. Searcher objects always represent a snapshot of an invindex as it existed when the Searcher was created. If you want the search results to reflect modifications to an invindex, you must create a new Searcher after the update process completes. COPYRIGHT
