# 安装过程    #

**下载源文件**

Xapian官网：[Xapiandownload page][]

**解压**

tar xf xapian-core-<versionnumber>.tar.xz
    tar xf xapian-omega-<versionnumber>.tar.xz
    tar xf xapian-bindings-<versionnumber>.tar.xz

**配置并创建Xapian库**

cd xapian-core-<version>
    ./configure
    make
    sudo make install

默认将安装在/usr/local目录下，可以根据自己的要求修改，参考 [官方安装指南][Link 1]。配置并创建Omega和Xapian-bindings的方式和这里类似。中间可能要安装几个额外的工具，否则无法继续上面的步骤， **一定要参考各自目录下的INSTALL文件**。

# 快速开始（测试） #

利用官方提供的快速开始方式来测试是否安装成功：[Quickstart][]。

代码如下：

//quickstartsearch.cc
    #include <xapian.h>
    #include <iostream>
    #include <stdlib.h>
    using namespace std;
    
    int main(int argc, char **argv) {
      if (argc < 3) {
        cout << "usage: " << argv[0] <<
        " <path to database> <search terms>" << endl;
        exit(1);
      }
      
      try {
        Xapian::Database db(argv[1]);
        Xapian::Enquire enquire(db);
        Xapian::Query query(Xapian::Query::OP_OR, argv + 2, argv + argc);
        cout << "Performing query '" << query.get_description() << "'" << endl;
        enquire.set_query(query);
        Xapian::MSet matches = enquire.get_mset(0, 10);
        cout << matches.size() << " results found" << endl;
        for (Xapian::MSetIterator i = matches.begin(); i != matches.end(); ++ i) {
           Xapian::Document doc = i.get_document();
           cout << "Document ID " << *i << "\t" <<
             i.get_percent() << "% [" << doc.get_data() << "]" << endl;
         }
      } catch (const Xapian::Error &error) {
        cout << "Exception: " << error.get_msg() << endl;
      }
    }

编译：g++ -o quickstartsearch quickstartsearch.cc \-lxapian 注意这里要加入xapian库进行编译，否则会出错。

运行：

$ ./quickstartindex proverbs \
    > "people who live in glass houses should not throw stones" \
    > people live glass house stone
    $ ./quickstartindex proverbs \
    > "Don't look a gift horse in the mouth" \
    > look gift horse mouth

$ ./quickstartsearch proverbs look
    Performing query `look'
    1 results found
    Document ID 2   50% [Don't look a gift horse in the mouth]
