[TYPO3-core] RFC #7158: Bug: Some parts of Indexed Search Engine Backend module don't work

[Moreno Feltscher]

I removed intval() because
1. item_type is VARCHAR (so '' is needed)
2. item_type examples are: '0', 'pdf', 'doc', 'xls'

Would be nice if this could be committed (I think, everyone who uses
DBAL would agree).
