Hello,
In the FTS/Limitations part of the documentation, it says :
"Another example — the PostgreSQL mailing list archives contained 910,989
unique words with 57,491,343 lexemes in 461,020 messages."
How could the number of lexemes be greater than unique words ?
Note the part with the hyphenated word example.

Thank you David for your response, it makes sense now.
