Hello Mirko, Try using fuzzy queries. You can do that by adding a tilde at the end of the term you're searching for, like PRIN3ER~. It uses the edit distance algorithm to find similar words. You can also specify the number of edits by adding the number after the tilde, for example, PRIN3ER~2 will match similar words up to two edits. Hope this helps.
