position_increment_gap
编辑position_increment_gap
编辑已分析的文本字段会考虑词项的位置,以便支持邻近或短语查询。当索引具有多个值的文本字段时,会在值之间添加一个“伪”间隔,以防止大多数短语查询跨值匹配。此间隔的大小使用 position_increment_gap
配置,默认为 100
。
例如
resp = client.index( index="my-index-000001", id="1", document={ "names": [ "John Abraham", "Lincoln Smith" ] }, ) print(resp) resp1 = client.search( index="my-index-000001", query={ "match_phrase": { "names": { "query": "Abraham Lincoln" } } }, ) print(resp1) resp2 = client.search( index="my-index-000001", query={ "match_phrase": { "names": { "query": "Abraham Lincoln", "slop": 101 } } }, ) print(resp2)
response = client.index( index: 'my-index-000001', id: 1, body: { names: [ 'John Abraham', 'Lincoln Smith' ] } ) puts response response = client.search( index: 'my-index-000001', body: { query: { match_phrase: { names: { query: 'Abraham Lincoln' } } } } ) puts response response = client.search( index: 'my-index-000001', body: { query: { match_phrase: { names: { query: 'Abraham Lincoln', slop: 101 } } } } ) puts response
const response = await client.index({ index: "my-index-000001", id: 1, document: { names: ["John Abraham", "Lincoln Smith"], }, }); console.log(response); const response1 = await client.search({ index: "my-index-000001", query: { match_phrase: { names: { query: "Abraham Lincoln", }, }, }, }); console.log(response1); const response2 = await client.search({ index: "my-index-000001", query: { match_phrase: { names: { query: "Abraham Lincoln", slop: 101, }, }, }, }); console.log(response2);
PUT my-index-000001/_doc/1 { "names": [ "John Abraham", "Lincoln Smith"] } GET my-index-000001/_search { "query": { "match_phrase": { "names": { "query": "Abraham Lincoln" } } } } GET my-index-000001/_search { "query": { "match_phrase": { "names": { "query": "Abraham Lincoln", "slop": 101 } } } }
这个短语查询不匹配我们的文档,这是完全预期的。 |

可以在映射中指定。例如
resp = client.indices.create( index="my-index-000001", mappings={ "properties": { "names": { "type": "text", "position_increment_gap": 0 } } }, ) print(resp) resp1 = client.index( index="my-index-000001", id="1", document={ "names": [ "John Abraham", "Lincoln Smith" ] }, ) print(resp1) resp2 = client.search( index="my-index-000001", query={ "match_phrase": { "names": "Abraham Lincoln" } }, ) print(resp2)
response = client.indices.create( index: 'my-index-000001', body: { mappings: { properties: { names: { type: 'text', position_increment_gap: 0 } } } } ) puts response response = client.index( index: 'my-index-000001', id: 1, body: { names: [ 'John Abraham', 'Lincoln Smith' ] } ) puts response response = client.search( index: 'my-index-000001', body: { query: { match_phrase: { names: 'Abraham Lincoln' } } } ) puts response
const response = await client.indices.create({ index: "my-index-000001", mappings: { properties: { names: { type: "text", position_increment_gap: 0, }, }, }, }); console.log(response); const response1 = await client.index({ index: "my-index-000001", id: 1, document: { names: ["John Abraham", "Lincoln Smith"], }, }); console.log(response1); const response2 = await client.search({ index: "my-index-000001", query: { match_phrase: { names: "Abraham Lincoln", }, }, }); console.log(response2);
