[BUGFIX] Avoid SQL error in indexed_search statistics

When an entered search word longer than 50 characters
was used in indexed_search previously, a TYPO3 Exception
was thrown due to a SQL error when having search statistics
enabled.

This change modifies the added statistic and cuts down
the search stats to a maximum length of 50 characters
as the DB field has only 50 characters.
