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