Perhaps you should try some spelling variations:
pensamiento politico » pensamiento critico
fajardo diego » fajardo rivero, gerardo diego, camargo diego
fajardo del » fajardo e, fajardo en, fajardo felix
pajaro del » pajaro de, pajaro en, pajaros de
fajardo y » fajardo la
dolci » dolfi

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: "((\"biblioteca saavedra ((fajardo y) OR (fajardo de)) pensamiento politico;\") or (\"biblioteca saavedra ((((((fajardo del) OR (fajardo dolci))) OR (fajardo diego))) OR (pajaro del)) pensamiento politico;\"))".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"biblioteca saavedra ((fajardo y) or (fajardo de)) pensamiento politico;\\") or (\\"biblioteca saavedra ((((((fajardo del) OR (fajardo dolci))) or (fajardo diego))) or (pajaro del)) pensamiento politico;\\"))\"".
• Removing quotes may allow a broader search: (( biblioteca saavedra ((fajardo y) or (fajardo de)) pensamiento politico; ) or ( biblioteca saavedra ((((((fajardo del) OR (fajardo dolci))) or (fajardo diego))) or (pajaro del)) pensamiento politico; )).
