Multi Lingual Searching

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.

dtSearch does not automatically find plurals of words entered in a search request, for example if you search for printer you will not find documents containing the word printers! With the stemming option selected it will find plurals and many other variations (e.g. 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 (e.g. verb and noun changes with gender) which do not occur in English, 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.
