Products.TextIndexNG-3.4.14-1.lbn25.noarch

Features:

• DocumentConverters StemmerSupport for 13 languages SimilaritySearch for english text (based on the Levenshtein distance) NearSearch, PluggableParsers extended StopWords support full integration in ZCatalog TestFunctionality through ZMI ExtensibleArchitecture being MoreEfficient than the current !TextIndex full globbing support (wildcard search) NormalizationSupport (e.g. reducing accented characters to their base form) full UnicodeAwareness Relevance ranking of search results added. Searches are now ranked using an extended cosine measure. The cosine measure is based on a vector model and calculates the document "score" based on the frequency of the query terms inside the document result set. Much faster phrase/near search: the old implementation of TextIndexNG had to perform a very expensive job at query time when phrase/near search was performed. Re-using the !WidCode module of !ZCTextIndex made this operation less expensive. Left-truncation added: TextIndexNG can be configured creation-time time to support left-truncation (means you can search for "suffix") Left-truncation is an option because this feature requires a second reverted index inside the lexicion and much more memory! optional auto-expansion support: This optional feature allows you to get better search results when some of the query terms could not be found. The index expands a query term "foo" to "foo" if there was no hit for "foo". This expansion is currently global for the index. This feature will be available on a per-query basis in a later version. (Auto-expansion will be extended in a later version to search for similiar terms) improved HTML converter: now using Chris Withers "Strip-o-Gram" module instead of the Strip-Tag-Parser added converter for text/sgml Similarity search (soundex, metaphone, doublemetaphone) dropped and replace with a more general approach and language indepedant approach using the Levenshtein distance. range searches like "Fi..Foo" * substring searches "substring"
