std::string ept::core::xapian::Source::toLower

(

const std::string &

str

)

[static, protected]

Return a lowercased copy of the string.

void ept::core::xapian::Source::normalize_and_add	(	Xapian::Document &	doc,
		const std::string &	term,
		int &	pos
	)			const [protected]

Add normalised tokens computed from the string to the document doc.

pos is used as a sequence generator for entering the token position in the document.
