[TYPO3] indexed_search limit results per page

[Michael Niemann]

hello,

I'm running TYPO3 4.1.6 and used the following to reduce the results from 100 to 10 per page:

plugin.tx_indexedsearch {
   search {
    _DEFAULT_PI_VARS.results = 10
   }
}

with no effect. Is there some other setting I can try?

Regards
Michael
