Perhaps you should try some spelling variations:
"intertextualitat" » "intertextuality", "interkulturalitat", "intertextualityitat", "intellectualitat", "intelectualitat"
"intelectualitat" » "intellektualitat", "intelectualidade", "intellectualist"
"intertextual" » "intertextuality", "intellectual", "intelectual"

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: (("intertextualitat" OR "intelectualitat") OR "intertextual").
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"intertextualitat\" OR \"intelectualitat\") or \"intertextual\")".
• Removing quotes may allow a broader search: (( intertextualitat OR intelectualitat ) or intertextual ).
• Adding a wildcard symbol may retrieve word variants: (("intertextualitat" OR "intelectualitat") or "intertextual")*.
