問題文
A search over clinical notes must ignore extremely common words and must also match inflected forms of a search term. Which two facts about the full-text engine support these needs? (Select two.)
選択肢
- A stoplist holds words that do not help the search and are ignored by full-text queries, and removing them from the index saves disk space.
- The pattern-matching predicate for character patterns performs the same linguistic analysis, so it can be used instead.
- Full-text queries are case-sensitive, so the team must normalize the case of the stored text before indexing.
- Thesaurus files hold the stopwords, so both needs are configured in one place.
- Each word breaker is associated with a language-specific stemmer that conjugates verbs and performs inflectional expansions.
