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 dolci
pajaro del » pajaro en, pajaros de, amaro del
fajardo y » fajardo la
pajaro de » pajarito de, paro de, pajaro verde

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 diego))) OR (((pajaro del) OR (pajaro de)))) 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 diego))) or (((pajaro del) OR (pajaro de)))) 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 diego))) or (((pajaro del) OR (pajaro de)))) pensamiento politico; )).
