The available full-text index can handle various combinations of the match options defined in the XQuery Full Text Recommendation. By default, most options are disabled. The GUI dialogs for creating new databases or displaying the database properties contain a tab for choosing between all available options. On the command-line, the <code>SET</code> command can be used to activate full-text indexing or creating a full-text index for existing databases:
* <code>SET FTINDEX ontrue; CREATE DB input.xml</code>
* <code>CREATE INDEX fulltext</code>
* '''Language''': [[#Languages|see below]] for more details (<code>SET LANGUAGE EN</code>)
* '''Support Wildcards''': a trie-based index can be applied to support wildcard searches (<code>SET WILDCARDS ONtrue</code>) * '''Stemming''': tokens are stemmed with the Porter Stemmer before being indexed (<code>SET STEMMING ONtrue</code>) * '''Case Sensitive''': tokens are indexed in case-sensitive mode (<code>SET CASESENS ONtrue</code>) * '''Diacritics''': diacritics are indexed as well (<code>SET DIACRITICS ONtrue</code>)
* '''TF/IDF Scoring''': TF/IDF-based scoring values are calculated and stored in the index (<code>SET SCORING 0/1/2</code>; details see below)
* '''Stopword List''': a stop word list can be defined to reduce the number of indexed tokens (<code>SET STOPWORDS [filename]</code>)
