Hello, I posted on the Lucene Forums, and someone told me to e-mail it here.
Instead of writing again my question here, I take the liberty to link my post. Its about SolR, autocompletion, Spellchecking and "case-sentivieness" (?). http://lucene.472066.n3.nabble.com/SolR-Spellchecking-amp-Autocomplete-td3243107.html Thanks for all, Valentin
