      • getIndexWord

        public IndexWord getIndexWord​(POS pos,
                                      String lemma)
        Description copied from class: Dictionary
        Look up a word in the database. The search is case-independent, and phrases are separated by spaces ("look up", not "look_up"). Note: this method does not subject lemma to any morphological processing. If you want this, use Dictionary.lookupIndexWord(POS, String).
        Specified by:
        getIndexWord in class Dictionary
        Parameters:
        pos - The part-of-speech.
        lemma - The orthographic representation of the word.
        Returns:
        An IndexWord representing the word, or null if no such entry exists.
      • getIndexWordIterator

        Description copied from class: Dictionary
        Return an Iterator over all the IndexWords of part-of-speech pos whose lemmas contain substring as a substring.
        Specified by:
        getIndexWordIterator in class Dictionary
        Parameters:
        pos - The part-of-speech.
        Returns:
        An iterator over IndexWords.

        Specified by:
        getIndexWordIterator in class Dictionary
        Parameters:
        pos - The part-of-speech
        Returns:
