将弹性搜索从1.4.3迁移到2.4代码

本文介绍了将弹性搜索从1.4.3迁移到2.4代码的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在从弹性搜索1.4.3迁移到2.4和
替换从弹性搜索文档和其他参考文献引用的代码，需要更换和Filter？

代码： -

  TermQueryBuilder incPlatformFilter = QueryBuilders.termQuery（IdxSchemaConstants.FULL_OFFER_ACTION_INCLUSIVE_PLATFORMS，platformId）; 
 
 //对于MissingQuerybuilder 
 // MissingFilterBuilder incPlatformEmptyFilter = FilterBuilders.missingFilter（IdxSchemaConstants.FULL_OFFER_ACTION_INCLUSIVE_PLATFORMS）; 
 BoolQueryBuilder incPlatformEmptyFilter = new BoolQueryBuilder（）。mustNot（new ExistsQueryBuilder（IdxSchemaConstants.FULL_OFFER_ACTION_INCLUSIVE_PLATFORMS））; 
 // NotFilterBuilder 
 // NotFilterBuilder excPlatformFilter = FilterBuilders.notFilter（FilterBuilders.termFilter（IdxSchemaConstants.FULL_OFFER_ACTION_EXCLUSIVE_PLATFORMS，platformId））; 
 TermQueryBuilder termQueryBuilder = QueryBuilders.termQuery（IdxSchemaConstants.FULL_OFFER_ACTION_EXCLUSIVE_PLATFORMS，platformId）; 
 BoolQueryBuilder excPlatformFilter = new BoolQueryBuilder（）。mustNot（termQueryBuilder）; 
 
 QueryBuilder platformPartialMatched = QueryHelper.andFilterBuilders（excPlatformFilter，incPlatformEmptyFilter）; 
 
 public class QueryHelper {
 public static QueryBuilder andFilterBuilders（QueryBuilder ... filterBuilders）{
 
 QueryBuilder filterBuilder = null; 
 
 if（filterBuilders！= null&& filterBuilders.length> 0）{
 
 filterBuilder = QueryBuilders.andFilter（filterBuilders）; 
} 
 return filterBuilder;} 
}

解决方案

您可以这样做：

  TermQueryBuilder incPlatformFilter = QueryBuilders.termQuery（IdxSchemaConstants.FULL_OFFER_ACTION_INCLUSIVE_PLATFORMS，platformId ）; 
 
 //对于MissingQuerybuilder 
 // MissingFilterBuilder incPlatformEmptyFilter = FilterBuilders.missingFilter（IdxSchemaConstants.FULL_OFFER_ACTION_INCLUSIVE_PLATFORMS）; 
 BoolQueryBuilder incPlatformEmptyFilter = new BoolQueryBuilder（）。mustNot（new ExistsQueryBuilder（IdxSchemaConstants.FULL_OFFER_ACTION_INCLUSIVE_PLATFORMS））; 
 // NotFilterBuilder 
 // NotFilterBuilder excPlatformFilter = FilterBuilders.notFilter（FilterBuilders.termFilter（IdxSchemaConstants.FULL_OFFER_ACTION_EXCLUSIVE_PLATFORMS，platformId））; 
 TermQueryBuilder termQueryBuilder = QueryBuilders.termQuery（IdxSchemaConstants.FULL_OFFER_ACTION_EXCLUSIVE_PLATFORMS，platformId）; 
 BoolQueryBuilder excPlatformFilter = new BoolQueryBuilder（）。mustNot（termQueryBuilder）; 
 
 // ==>使用布尔值/过滤器替换和查询<< == 
 QueryBuilder platformPartialMatched = QueryBuilders.boolQuery（）
 .filter（excPlatformFilter）
 .filter（incPlatformEmptyFilter）;

I am migrating from elastic search 1.4.3 to 2.4 andreplaced piece of code referred from elastic search docs and other references need replacement of andFilter?

Code:-

  TermQueryBuilder incPlatformFilter=QueryBuilders.termQuery(IdxSchemaConstants.FULL_OFFER_ACTION_INCLUSIVE_PLATFORMS, platformId);

  //For MissingQuerybuilder
  //MissingFilterBuilder incPlatformEmptyFilter = FilterBuilders.missingFilter(IdxSchemaConstants.FULL_OFFER_ACTION_INCLUSIVE_PLATFORMS);
  BoolQueryBuilder incPlatformEmptyFilter = new BoolQueryBuilder().mustNot(new ExistsQueryBuilder(IdxSchemaConstants.FULL_OFFER_ACTION_INCLUSIVE_PLATFORMS));
  //NotFilterBuilder
  //NotFilterBuilder excPlatformFilter = FilterBuilders.notFilter(FilterBuilders.termFilter(IdxSchemaConstants.FULL_OFFER_ACTION_EXCLUSIVE_PLATFORMS, platformId));
  TermQueryBuilder termQueryBuilder = QueryBuilders.termQuery(IdxSchemaConstants.FULL_OFFER_ACTION_EXCLUSIVE_PLATFORMS, platformId);
  BoolQueryBuilder excPlatformFilter = new BoolQueryBuilder().mustNot(termQueryBuilder);

  QueryBuilder platformPartialMatched = QueryHelper.andFilterBuilders(excPlatformFilter, incPlatformEmptyFilter);

  public class QueryHelper {
    public static QueryBuilder andFilterBuilders(QueryBuilder... filterBuilders) {

     QueryBuilder filterBuilder = null;

      if (filterBuilders != null && filterBuilders.length > 0) {

  filterBuilder = QueryBuilders.andFilter(filterBuilders);
}
return filterBuilder;}
}

解决方案

You can do it like this:

TermQueryBuilder incPlatformFilter = QueryBuilders.termQuery(IdxSchemaConstants.FULL_OFFER_ACTION_INCLUSIVE_PLATFORMS, platformId);

//For MissingQuerybuilder
//MissingFilterBuilder incPlatformEmptyFilter = FilterBuilders.missingFilter(IdxSchemaConstants.FULL_OFFER_ACTION_INCLUSIVE_PLATFORMS);
BoolQueryBuilder incPlatformEmptyFilter = new BoolQueryBuilder().mustNot(new ExistsQueryBuilder(IdxSchemaConstants.FULL_OFFER_ACTION_INCLUSIVE_PLATFORMS));
//NotFilterBuilder
//NotFilterBuilder excPlatformFilter = FilterBuilders.notFilter(FilterBuilders.termFilter(IdxSchemaConstants.FULL_OFFER_ACTION_EXCLUSIVE_PLATFORMS, platformId));
TermQueryBuilder termQueryBuilder = QueryBuilders.termQuery(IdxSchemaConstants.FULL_OFFER_ACTION_EXCLUSIVE_PLATFORMS, platformId);
BoolQueryBuilder excPlatformFilter = new BoolQueryBuilder().mustNot(termQueryBuilder);

// ==> use a bool/filter to replace the "and" query <<==
QueryBuilder platformPartialMatched = QueryBuilders.boolQuery()
    .filter(excPlatformFilter)
    .filter(incPlatformEmptyFilter);
