With a truncation you can search a word stem with all possible endings. To do this, place a character at the end of the root of a search term that is a placeholder for potential word endings (right truncation).
Example: "eco*" finds (among others) "economics", "economist", "ecosystem", etc.
Masking - insert wildcard:
Masking allows you to replace only a single character within a search term with a wildcard.
Example: "mi?rosensor" finds "microsensor" or "Mikrosensor".
Truncation and masking characters can vary from one information tool to another. Often the characters * or ? or $ are used. Please refer to the help texts of your information tool.
