1、文件系统数据构造
PUT /fs
{
"settings": {
"analysis": {
"analyzer": {
"paths": {
"tokenizer": "path_hierarchy"
}
}
}
}
}
path_hierarchy tokenizer讲解
/a/b/c/d --> path_hierarchy -> /a/b/c/d, /a/b/c, /a/b, /a
fs: filesystem
PUT /fs/_mapping/file
{
"properties": {
"name": {
"type": "keyword"
},
"path": {
"type": "keyword",
"fields": {
"tree": {
"type": "text",
"analyzer": "paths"
}
}
}
}
}
PUT /fs/file/1
{
"name": "README.txt",
"path": "/workspace/projects/helloworld",
"contents": "这是我的第一个elasticsearch程序"
}
2、对文件系统执行搜索
文件搜索需求：查找一份，内容包括elasticsearch，在/workspace/projects/hellworld这个目录下的文件
GET /fs/file/_search
{
"query": {
"bool": {
"must": [
{
"match": {
"contents": "elasticsearch"
}
},
{
"constant_score": {
"filter": {
"term": {
"path": "/workspace/projects/helloworld"
}
}
}
}
]
}
}
}
{
"took": 2,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"failed": 0
},
"hits": {
"total": 1,
"max_score": 1.284885,
"hits": [
{
"_index": "fs",
"_type": "file",
"_id": "1",
"_score": 1.284885,
"_source": {
"name": "README.txt",
"path": "/workspace/projects/helloworld",
"contents": "这是我的第一个elasticsearch程序"
}
}
]
}
}
搜索需求2：搜索/workspace目录下，内容包含elasticsearch的所有的文件
/workspace/projects/helloworld doc1
/workspace/projects doc1
/workspace doc1
GET /fs/file/_search
{
"query": {
"bool": {
"must": [
{
"match": {
"contents": "elasticsearch"
}
},
{
"constant_score": {
"filter": {
"term": {
"path.tree": "/workspace"
}
}
}
}
]
}
}
}
