1、java-api
SearchRequest request = new SearchRequest(index);
// 构建一个SearchSourceBuilder
SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
// 添加查询条件
BoolQueryBuilder boolQueryBuilder = QueryBuilders.boolQuery();
if(StringUtils.isNotBlank(basyName)){
boolQueryBuilder.must(QueryBuilders.matchQuery("content", basyName).analyzer(ANALYZER)); // 替换为你的字段名和查询关键词
}
boolQueryBuilder.must(QueryBuilders.termQuery("hdfsType",StatusEnum.TYPE_SHENJIYIJU.getFlag()));
searchSourceBuilder.query(
boolQueryBuilder.must(QueryBuilders.termQuery("status",StatusEnum.STATUS_YES.getFlag()))
.must(QueryBuilders.termQuery("fileSourceType",StatusEnum.FILE_SOURCE_TYPE_HDFS.getFlag()))
);
/*高亮查询*/
HighlightBuilder highlightBuilder = new HighlightBuilder();
highlightBuilder.preTags("<span style='color:red;'>");
highlightBuilder.postTags("</span>");
highlightBuilder.field("content");
/*需要highlightBuilder，前面创建好*/
searchSourceBuilder.highlighter(highlightBuilder);
// 将SearchSourceBuilder设置到SearchRequest中
request.source(searchSourceBuilder);
request.scroll(TimeValue.timeValueMinutes(1L));
SearchResponse search = null;
try {
search = client.search(request, RequestOptions.DEFAULT);
} catch (IOException e) {
e.printStackTrace();
}
SearchHits hits = search.getHits();
//总条数
long totalLong =hits.getTotalHits().value;
SearchHit[] hitsArr = hits.getHits();
List<FileContentInf> contentInfs = new ArrayList<>();
for (SearchHit documentFields : hitsArr) {
String json = documentFields.getSourceAsString();
FileContentInf inf = JSONObject.parseObject(json, FileContentInf.class);
if(documentFields.getHighlightFields()!=null && documentFields.getHighlightFields().get("content")!=null){
Text[] contents = documentFields.getHighlightFields().get("content").getFragments();
if(contents.length>0){
inf.setContentInfHtml(contents[0].toString());
}
}
contentInfs.add(inf);
}
String scrollId = search.getScrollId();
while (hitsArr!=null && hitsArr.length>0){
// 创建一个新的SearchScrollRequest
SearchScrollRequest scrollRequest = new SearchScrollRequest(scrollId);
scrollRequest.scroll(TimeValue.timeValueMinutes(1L)); // 设置scroll超时
// 执行scroll查询
SearchResponse scrollResponse = client.scroll(scrollRequest, RequestOptions.DEFAULT);
scrollId = scrollResponse.getScrollId();
hitsArr = scrollResponse.getHits().getHits();
for (SearchHit documentFields : hitsArr) {
String json = documentFields.getSourceAsString();
FileContentInf inf = JSONObject.parseObject(json, FileContentInf.class);
if(documentFields.getHighlightFields()!=null && documentFields.getHighlightFields().get("content")!=null){
Text[] contents = documentFields.getHighlightFields().get("content").getFragments();
if(contents.length>0){
inf.setContentInfHtml(contents[0].toString());
}
}
contentInfs.add(inf);
}
}
// 清除scroll
ClearScrollRequest clearScrollRequest = new ClearScrollRequest();
clearScrollRequest.addScrollId(scrollId);
client.clearScroll(clearScrollRequest, RequestOptions.DEFAULT);
// 设置排序规则为降序
searchSourceBuilder.sort("updateTime.keyword", SortOrder.DESC); // 替换为你要排序的字段名
// 设置分页参数
searchSourceBuilder.from((pageResult.getPageNum()-1) * pageResult.getPageSize());
searchSourceBuilder.size(pageResult.getPageSize());
2、kibana常用命令
按照条件查找
POST /file_content_inf/_search
{
"query": {
"match": {
"fileId": "f8883aed62c27abd6b20013be23db408"
}
}
}
GET /file_content_inf/_search
{
"query": {
"match": {
"content": "文件"
}
}
}
按照条件删除：
POST /file_content_inf/_delete_by_query
{
"query": {
"match": {
"fileId": "f8883aed62c27abd6b20013be23db408"
}
}
}
删除索引：
DELETE /file_content_inf
