Perhaps you should try some spelling variations:
"very scarce telescopes" » "very space telescope", "very large telescopes", "very star telescopes"
"very space telescopes" » "very space telescope", "very sparse telescopes", "query space telescopes", "key space telescopes"
"very large telescope" » "very large telescopes"

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: (((("very space telescopes") OR ("very scarce telescopes"))) OR ("very large telescope")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"very space telescopes\") OR (\"very scarce telescopes\"))) or (\"very large telescope\"))".
• Removing quotes may allow a broader search: (((( very space telescopes ) OR ( very scarce telescopes ))) or ( very large telescope )).
• Adding a wildcard symbol may retrieve word variants: (((("very space telescopes") OR ("very scarce telescopes"))) or ("very large telescope"))*.
