I have confirmed that this is fixed, however the results are pretty irrelevent to C++ :)
I'll have to dig further hehe
This is a tokenizer issue. Searches for "C++" are interpreted as searches for "c".
To see how queries are tokenized, parsed and translated try:
% bin/nutch net.nutch.searcher.Query
Queries are first tokenized, using the same tokenizer as is used for documents. Query tokens are next parsed into instances of net.nutch.searcher.Query, interpreting plusses, minuses and quotes. The parsed query is displayed using Nutch's query syntax, described at http://www.nutch.org/docs/en/help.html.
Finally Nutch queryeis are translated into Lucene queries (instances of org.apache.lucene.search.Query). The translated query is displayed using Lucene's query syntax, described at http://jakarta.apache.org/lucene/docs/queryparsersyntax.html.
The tokenizer could be altered to better handle "C++". The file to edit is NutchAnalysis.jj. The 'generate-src' ant target runs JavaCC, to generate NutchAnalysis.java. JavaCC documentation can be found at https://javacc.dev.java.net/.
