1.查询全部
1.1 java
代码语言：javascript
复制 esBlogRepositoryl.findAll();
1.2 es
代码语言：javascript
复制GET /blog/_search
{
"query": {
"match_all": {
"boost": 1
}
}
}
2.模糊查询
2.1 java
代码语言：javascript
复制 //fuzziness 即为最多纠正两个字母然后去匹配，默认为 auto（2）
FuzzyQueryBuilder fuzzyQueryBuilder = QueryBuilders.fuzzyQuery("title", "springboot1");
System.out.println(fuzzyQueryBuilder);
Iterable<EsBlog> search = esBlogRepositoryl.search(fuzzyQueryBuilder);
System.err.println("==============================================");
search.forEach(x->{
System.out.println(x);
});
2.2 es
代码语言：javascript
复制GET /blog/_search
{
"query": {
"fuzzy": {
"title": {
"value": "springboot",
"fuzziness": "AUTO",
"prefix_length": 0,
"max_expansions": 50,
"transpositions": false,
"boost": 1
}
}
}
}
3.and查询
3.1 java
代码语言：javascript
复制 BoolQueryBuilder queryBuilders = QueryBuilders.boolQuery();
queryBuilders.must(QueryBuilders.matchPhraseQuery("title", "springboot"));
queryBuilders.must(QueryBuilders.matchPhraseQuery("content", "springboot"));
System.out.println(queryBuilders.toString());
Iterable<EsBlog> search = esBlogRepositoryl.search(queryBuilders);
System.err.println("==============================================");
search.forEach(x -> {
System.out.println(x);
});
3.2 es
代码语言：javascript
复制GET /blog/_search
{
"query": {
"bool": {
"must": [
{
"match_phrase": {
"title": {
"query": "springboot",
"slop": 0,
"zero_terms_query": "NONE",
"boost": 1
}
}
},
{
"match_phrase": {
"content": {
"query": "springboot",
"slop": 0,
"zero_terms_query": "NONE",
"boost": 1
}
}
}
],
"adjust_pure_negative": true,
"boost": 1
}
}
}
4.or查询
4.1 java
代码语言：javascript
复制 BoolQueryBuilder queryBuilders = QueryBuilders.boolQuery();
queryBuilders.should(QueryBuilders.matchPhraseQuery("title", "springboot1"));
queryBuilders.should(QueryBuilders.matchPhraseQuery("content", "springboot"));
System.out.println(queryBuilders.toString());
Iterable<EsBlog> search = esBlogRepositoryl.search(queryBuilders);
System.err.println("==============================================");
search.forEach(x -> {
System.out.println(x);
});
4.2 es
代码语言：javascript
复制GET /blog/_search
{
"query": {
"bool": {
"should": [
{
"match_phrase": {
"title": {
"query": "springboot1",
"slop": 0,
"zero_terms_query": "NONE",
"boost": 1
}
}
},
{
"match_phrase": {
"content": {
"query": "springboot",
"slop": 0,
"zero_terms_query": "NONE",
"boost": 1
}
}
}
],
"adjust_pure_negative": true,
"boost": 1
}
}
}
5.分页并按照id倒叙
5.1 java
代码语言：javascript
复制 BoolQueryBuilder queryBuilders = QueryBuilders.boolQuery();
queryBuilders.must(QueryBuilders.matchPhraseQuery("title", "springboot"));
System.out.println(queryBuilders.toString());
Pageable pageable = PageRequest.of(0, 2, Sort.Direction.DESC,"createTime");
Page<EsBlog> search = esBlogRepositoryl.search(queryBuilders, pageable);
System.out.println(search);
List<EsBlog> content = search.getContent();
System.err.println("==============================================");
content.forEach(x->{
System.out.println(x);
});
5.2 es
代码语言：javascript
复制GET /blog/_search
{
"query": {
"bool": {
"must": [
{
"match_phrase": {
"title": {
"query": "springboot",
"slop": 0,
"zero_terms_query": "NONE",
"boost": 1
}
}
}
],
"adjust_pure_negative": true,
"boost": 1
}
}
}
名称解释
- boost：搜索条件的权重，可以将某个搜索条件的权重加大。此时当匹配这个搜索条件和匹配另一个搜索条件的document，计算relevance score时，匹配权重更大的搜索条件的document，relevance score会更高，当然也就会优先被返回回来
