Perhaps you should try some spelling variations:
"prism library wrappers" » "prism library proper", "prism library apps", "prism library leaders", "from library wrappers", "itsm library wrappers"
"ilm library pattern" » "ilm library patterns", "ilm binary pattern", "ilm dietary pattern", "itsm library pattern", "from library pattern", "form library pattern"
"prism library headers" » "prism library managers", "from library headers", "itsm library headers"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("ilm library pattern") OR ((("prism library wrappers") OR ("prism library headers")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"ilm library pattern\") or (((\"prism library wrappers\") OR (\"prism library headers\"))))".
• Removing quotes may allow a broader search: (( ilm library pattern ) or ((( prism library wrappers ) OR ( prism library headers )))).
• Adding a wildcard symbol may retrieve word variants: (("ilm library pattern") or ((("prism library wrappers") OR ("prism library headers"))))*.
