> Because of some backwards compatibility problems (LUCENE-1906) we changed the CharStream/CharFilter
API a little bit. Tokenizer now only has a input field of type java.io.Reader (as before the
CharStream code). To correct offsets, it is now needed to call the Tokenizer.correctOffset(int)
method, which delegates to the CharStream (if input is subclass of CharStream), else returns
an uncorrected offset. Normally it is enough to change all occurences of input.correctOffset()
to this.correctOffset() in Tokenizers. It should also be checked, if custom Tokenizers in
Solr do correct their offsets.
