parse

                                                    org.apache.hadoop.conf.Configuration conf)

Does fixup on the passed in query before giving it into nutch. Preprocess the query to do special handling of 'exacturl' clause if present. Split on spaces and then for each term, look for one that begins 'exacturl'. If we find one, special-encode its value. Do an encoding that is neither url nor html. Same encoding must be done in index-exacturl. This custom encoding is necessary because NutchAnalysis will not let through '?' or '=' characters in clause values and the '&' character can't be passed in a query string because it'll confuse request.getParameter.

Parameters:

queryString - Query string.

conf -

Returns:

Analyzed query.

Throws:

java.io.IOException
