Summary
dtSearch Language Extension Packs by dtSearch Corp.
Multi lingual searching. dtSearch Engine/Web is supplied with stemming rules and a noise-word file for English(US). If you are searching documents written in other languages then this could mean that plurals and noise words are missed. ElectronArt Language Extension Packs are available for Eastern and Western European languages to improve your non English(US) search results.
Language Extension Pack series 400 (ElectronArt )
For dtSearch Text Retrieval Engine or Web 6.5 or later.
dtSearch Engine/Web is supplied with stemming rules and a noise-word file for English(US). Stemming is the only search expansion option which is 'on' by default in the dtSearch end-user products; the reason for this is that stemming is almost always useful when making a search, and adds little to the time required to make a search. Unlike some other search engines, dtSearch applies stemming at search time, there is no need to build indexes specifically to apply stemming and no need to build separate indices for each language in use.
The problem
With the stemming option selected dtSearch will find plurals and many other variations; for example a search on print will find printers, printing, printed automatically. However, if you are searching documents written in other languages, the English stemming rules will cause you to miss many word variations which do not occur in English (e.g. verb and noun changes with gender), and you may find that words which are unrelated are found in error.
Furthermore, the English noise word list, which is designed to remove unwanted English words from your index to keep the index size small, is not suitable for other languages; your indexes may contain many words which will not be useful in searches and which will add to the size of your indexes.
The solution
Use language specific files in place of the default US English files. These are supplied in the form of Language Extension Packs which contain files for many languages, see list below. All files are in Unicode format.
