At indexing time, Solr does not treat the hyphen as a special character like it does at query time. Many analysis components do, though. If your analysis chain includes certain components (the standard tokenizer, the ICU tokenizer, and WordDelimeterFilter are on that list), then the hypen may be treated as a word break character and the analysis could remove it. At query time, a hyphen in the middle of a word is not treated as a special character. It would need to be at the beginning of the query text or after a space for the query parser to treat it as a negation. So Wainui-8 would not be a problem, but -7 would, and you'd need to specify it as \-7 for it to work like you want. Thanks, Shawn
