• If you are trying to use Boolean operators, they must be ALL CAPS: (((("literatura en debate.") OR ("literatura espana debate."))) OR ("literatura espanol datos."))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"literatura en debate.\") OR (\"literatura espana debate.\"))) or (\"literatura espanol datos.\"))~".
• Removing quotes may allow a broader search: (((( literatura en debate. ) OR ( literatura espana debate. ))) or ( literatura espanol datos. ))~.
• Adding a wildcard symbol may retrieve word variants: (((("literatura en debate.") OR ("literatura espana debate."))) or ("literatura espanol datos."))*.
