Perhaps you should try some spelling variations:
physical collected » physical collection, medical collected, partial collected
"Solid surface physical Collected works." » "Solid surface physics Collected works.", "Solid surfaces physics Collected works.", "Solid surface chemical Collected works.", "Solid surface physical Collected work."
solid surface » solid surfaces, solids surfaces, road surface
"solid state physics collected works." » "solid states physics collected works.", "solid state physics collected work."

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("solid state physics collected works.") or ("Solid surface physical Collected works."))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("solid state physics collected works.") OR ("Solid surface physical Collected works.")).
• Removing quotes may allow a broader search: (( solid state physics collected works. ) or ( Solid surface physical Collected works. )).
• Adding a wildcard symbol may retrieve word variants: (("solid state physics collected works.") or ("Solid surface physical Collected works."))*.
