Quest - 搜索查询和测试工具 ($version)

用法
    {$_SERVER['argv'][0]} [options] [-p|--project] <project> [[-q|--query] <query>]
	
选项说明
    --project=<name|ini>
    -p <project> 用于指定要搜索的项目名称或项目配置文件的路径，
                 如果指定的是名称，则使用 ../app/<name>.ini 作为配置文件
    --charset=<gbk|utf-8>
    -c <charset> 指定您当前在用的字符集，以便系统进行智能转换（默认：UTF-8）
    --db=<name[,name2 ...]>
    -d <db[,db2 ...]> 指定项目中的数据库名称，默认是名为 db 的库，多个库之间用逗号分隔
    --query=<query>
    -q <query>   指定要搜索的查询语句，如果语句中包含空格请用使用双引号包围起来
                 在搜索语句中可采用 'field:\$from..\$to' 做区间过滤
    --sort=<field1[,field2[,...]]
    -s <field1[,field2[,...]] 指定排序字段，在字段前加上 ~ 符号表示逆序
    --fuzzy      将搜索默认设为模糊搜索
    --synonym[=scale]
                 开启自动同义词搜索功能，可选择设置同义词权重调整（0.01~2.55）
    --scws-multi=<level>
                 查看或设置搜索语句的 scws 复合分词等级（值：0-15，默认为 3）
    --add-weight=<[field1:]word1[:weight1][,[field2:]word2[:weight2]]>
                 添加搜索权重词汇，词与次数之间用半角冒号分隔
    --hot[=total|last|cur]
                 用于显示指定项目的热门搜索词，此时 <query> 参数无意义，可省略
                 其值含义分别表示总搜索量、上周搜索量、本周搜索量，默认为总搜索量。
    --suggest    根据当前搜索词展开常用搜索词建议，如查询“中”，即显示“中”开头的词
    --correct    根据当前搜索词进行同音、拼写纠错，输出更合适的关键词
    --related    根据当前搜索词查找相关搜索词
    --list-synonyms[=stemmed]
                 列出库内的全部同义词，每行显示一个，可以搭配 --limit 使用，默认显示前 100 个
                 如果设置了 stemmed 值则连同词根同义词也列出，设置其它值则只列出指定词的全部同义词
    --limit=<num>用于设置 suggest|hot|related 的返回数量，两者默认值均为 10 个
                 对于普通搜索和列出同义词时，还支持用 --limit=offset,num 的格式
    --show-query 用于在搜索结果显示内部的 Xapian 结构的 query 语句用于调试
    --cut-off=<percent[,weight>
                 设置搜索结果剔除的匹配百分比及权限（百分比：0-100，权重：0.1-25.5）
    --terms      列出搜索词被切分后的词（不含排除及权重词）
    --info       显示当前连接服务端的信息及线程（仅绘制当前 worker 进程）
    -h|--help    显示帮助信息

    若未指定 -p 或 -q 则会依次把附加的参数当作 <project> 和 <query> 处理，例：
    {$_SERVER['argv'][0]} <project> <query>
    {$_SERVER['argv'][0]} --hot <project>
