Summary of the findings.

Familiarity group	Characteristic frequent patterns
L1	More likely to reformulate the query: the proportion of frequent patterns that contained a modified query (Q:ModQ) was higher than that containing the first query (Q:NewQ).
	More likely to encounter difficulty during the search process, eg, they frequently accessed irrelevant websites and had a low search efficiency.
	Discovery of relevant webpages (information source) more frequently in the results were retrieved with the modified query than the first query.
L2	More likely to reformulate the query: the proportion of frequent patterns that contained a modified query (Q:ModQ) was higher than that containing the first query (Q:NewQ).
	Discovery of relevant webpages (information source) more frequently in the results were retrieved with the modified query than the first query.
	Achievement of better search efficiency than group L1.
	Continuation of the search process after discovering relevant webpages by issuing another query.
L3	Access of consumer health information websites directly to start the search session.
	Discovery of relevant webpages (information source) more frequently in the results were retrieved with the first query than the modified query.
	Continuation of the search process by issuing another query or by reexamining the results retrieved.
