Question

我有一个lucene搜索，我试图用LanguageIds过滤我的搜索，但我无法做到这一点。我正在传递我的Languageids，如“1,2,3”，但它没有正确过滤，它只采用了带有languageIds“1,2,3”的值。但我想要的结果是languageIds为“1”，“1,2”，“1,3”，“1,2,3”。任何机构都可以告诉我如何在Lucene.net中为单个termQuery传递多个值吗？

我迄今为止做过的是

          if (languagelds.Contains(","))
            {
                List<String> languageld = languagelds.Trim().Split(',').ToList();
                languageld.ForEach(lid =>
                {
                    TermQuery languageQuery = new TermQuery(new Term("resourceLanguageIds", lid));
                    filterQuery.Add(languageQuery, BooleanClause.Occur.MUST);
                });
            }
            else
            {
                TermQuery languageQuery = new TermQuery(new Term("resourceLanguageIds", languagelds));
                filterQuery.Add(languageQuery, BooleanClause.Occur.MUST);
            }


        filterQuery.Add(productQuery, BooleanClause.Occur.MUST);
        Filter filter = new CachingWrapperFilter(new QueryWrapperFilter(filterQuery));
        TopScoreDocCollector collector = TopScoreDocCollector.create(100, true);
        Hits hits = null;
        if (sortField != "Rank")
        {
            hits = indexSearch.Search(searchQuery, filter, sort);
            indexSearch.SetDefaultFieldSortScoring(true, true);
        }
        else
        {
            hits = indexSearch.Search(searchQuery, filter);
        }

你可以尝试多次添加相同的字段，同时索引像

doc.Add( new Field(resourceLanguageId,"1"... 

doc.Add( new Field(resourceLanguageId,"2"...

doc.Add( new Field(resourceLanguageId,"3"...

如何使用2个值过滤Lucene搜索？
