[Xapian-discuss] Query::MatchAll

[Allen]

O.K. here is the quickstartindex.cpp

#include <xapian.h>
#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{
    if (argc < 4) {
        cout << "usage: " << argv[0] << "<path to database>" <<
            " <document data> <document terms>" << endl;
        return EXIT_FAILURE;
    }

    try {
        Xapian::WritableDatabase database(argv[1],
Xapian::DB_CREATE_OR_OPEN);
        Xapian::Document newdocument;
        newdocument.set_data(string(argv[2]));
        for (int i(3); i < argc; ++i) {
            newdocument.add_posting(argv[i], i-2);
        }
        database.add_document(newdocument);
    }
    catch (const Xapian::Error &e) {
        cout << "Xapian.Error: " << e.get_msg() << endl;
    }

    return EXIT_SUCCESS;
}

and the quickstartsearchall.cpp

#include <xapian.h>
#include <iostream>

using namespace std;
using namespace Xapian;

int main(int argc, char *argv[])
{
    if (argc < 2) {
        cout << "usage: " << argv[0] << " <path to database>" << endl;
        return EXIT_FAILURE;
    }

    try {
        Database db(argv[1]);
        Enquire enquire(db);
        enquire.set_query(Query::MatchAll);
        MSet matches = enquire.get_mset(0, 10);
        cout << matches.size() << " results found" << endl;
        for (MSetIterator i = matches.begin(); i != matches.end(); i++) {
            Document doc = i.get_document();
            cout << "#" << *i << "\t" << i.get_percent() << "% [" <<
                doc.get_data() << "]" << endl;
        }
    }
    catch (const Error &e) {
        cout << "Xapian.Error: " << e.get_msg() << endl;
    }

    return EXIT_SUCCESS;
}
