String search

The Extended Lucene string search indexing supports the default search, as well as :contains, :exact, and :text modifiers.

The default (unmodified) string search matches by prefix, insensitive to case or accents.

:exact matches the entire string, matching case and accents.

:contains match any substring of the text, ignoring case and accents.

:text provides a rich search syntax.
