• Performing a fuzzy search may retrieve terms with similar spellings: (("thep binh nam dinh ngoc.") or ((("thep hanh nam trung doc.") OR ("thep hanh ngay trung doc."))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("thep binh nam dinh ngoc.") OR ((("thep hanh nam trung doc.") OR ("thep hanh ngay trung doc.")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"thep binh nam dinh ngoc.\") or (((\"thep hanh nam trung doc.\") OR (\"thep hanh ngay trung doc.\"))))".
• Removing quotes may allow a broader search: (( thep binh nam dinh ngoc. ) or ((( thep hanh nam trung doc. ) OR ( thep hanh ngay trung doc. )))).
• Adding a wildcard symbol may retrieve word variants: (("thep binh nam dinh ngoc.") or ((("thep hanh nam trung doc.") OR ("thep hanh ngay trung doc."))))*.
