@ -601,18 +601,50 @@ Options available:
titles: Hashmap or array of tiddler titles to limit search
exclude: An array of tiddler titles to exclude from the search
invert: If true returns tiddlers that do not contain the specified string
caseSensitive: If true forces a case sensitive search
literal: If true, searches for literal string, rather than separate search terms
