I tried to use WildcardFilter so i sub-classed QueryParser and reimplemented
getWildcardQuery function
CL_NS(search)::Query* WildQueryParser::getWildcardQuery(const TCHAR* _field,
TCHAR* termStr)
{
Query * query = QueryParser::getWildcardQuery(_field, termStr);
const char * objectName = query->getObjectName();
if(strcmp(objectName, "WildcardQuery") == 0)
{
// _CLDELETE(objectName);
Term* t = _CLNEW Term(_field, termStr);
WildcardFilter * f = new WildcardFilter(t);
Query* q = new ConstantScoreQuery(f);
// _CLDELETE(t);
return q;
}
// _CLDELETE(objectName);
return query;// now query is not wildcardQuery so i will return it as it is.
}
and it searches without any errors and return the results correctly.
but when i tried to highlight search results i got the following error
terminate called after throwing an instance of 'std::logic_error'
what(): basic_string::_S_construct NULL not valid
so i tried to debug and see where is the problem but i am lost in code but i
think the problem
is in the function
TextFragment** Highlighter::getBestTextFragments(
StringBuffer* writeTo,
TokenStream * tokenStream,
const TCHAR* text,
bool mergeContiguousFragments,
int32_t maxNumFragments)
I tried to debug this function many times , I don't know if i am doing
something wrong or not?
