• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"under delta development comparison program.\") OR (\"web sme development complex problems.\"))~".
• Removing quotes may allow a broader search: (( under delta development comparison program. ) OR ( web sme development complex problems. ))~.
• Adding a wildcard symbol may retrieve word variants: (("under delta development comparison program.") OR ("web sme development complex problems."))*.
