Quickwit：亚秒级延迟的对象存储搜索引擎
如果用过 ES，会感到非常熟悉，具体包括以下步骤：
第一步：编写索引配置文件 wiki_index_config.json（以 wiki 为例），保存到当前目录：
{
"default_search_fields": ["body", "title"], // If you do not specify fields in your query, those fields will be used.
"field_mappings": [
{
"name": "body",
"type": "text"
},
{
"name": "title",
"type": "text"
},
{
"name": "url",
"type": "text",
"indexed": false, // Field not indexed, you will not be able to search on this field.
"stored": false // Field not stored.
}
]
}
第二步：创建索引：
$ ./quickwit new --index-uri file:///$(pwd)/wikipedia --index-config-path ./wiki_index_config.json
其中，wikipedia 是空文件夹
第三步：添加一些文档（需提前下载文档文件到当前目录）：
./quickwit index --index-uri file:///$(pwd)/wikipedia --input-path wiki-articles-10000.json
文档看起来是这样：
$ head -1 wiki-articles-10000.json
{"url":"https://en.wikipedia.org/wiki?curid=48687903","title":"Jeon Hye-jin (actress, born 1988)","body":"\nJeon Hye-jin (actress, born 1988)\n\nJeon Hye-jin (born June 17, 1988) is a South Korean actress.\nPersonal life.\nJeon married his \"Smile, You\" co-star Lee Chun-hee on March 11, 2011. Their daughter, Lee So Yu, was born on July 30, 2011.\n\n"}
第四步：启动 Server：
$ ./quickwit serve --index-uri file:///$(pwd)/wikipedia
然后就可以进行 Query 了：
$ curl "http://0.0.0.0:8080/api/v1/wikipedia/search?query=barack+AND+obama"
# 指定 field
$ curl "http://0.0.0.0:8080/api/v1/wikipedia/search?query=body:barack+AND+obama"
文件目录如下：
$ tree . -L 2
.

噢，差点忘了，它还同时提供 gRPC 接口，默认 8082 端口；）
