Does Texis do "stemming"? How about in other languages?

Stemming refers to a process of stripping a word down to its root by removing suffixes or prefixes (such as the "s" on the end of English plurals), and then searching for valid variations of the root (known as morphemes). Texis provides very sophisticated morpheme processing, with default rules that apply to English. Various aspects of morpheme processing may be turned on or off, and the rules customized. A set of morpheme processing rules may be specified for any language. However, we are not linguists and have not defined the stripping and rebuilding rules for most other languages. A user organization typically will wish to customize these rules not only for your language, but for a particular type of data or search style.
