如何用 2 个值过滤 Lucene 搜索？
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。我传递了像“1,2,3”这样的语言ID，但它没有正确过滤，它只接受具有语言ID“1,2,3”的值。但我希望结果的 languageId 为“1”、“1,2”、“1,3”、“1,2,3”。谁能告诉我如何在 Lucene.net 中为单个 termQuery 传递多个值？
到目前为止我所做的是
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);
}
I have a lucene search where i was trying to filter my search with LanguageIds, but i was unable to do that. I was passing my Languageids like "1,2,3",but its not filtering correctly,its only taking values having languageIds "1,2,3". but i want results having languageIds with "1", "1,2", "1,3", "1,2,3". Can any body tell me how to pass multiple values for a single termQuery in Lucene.net?
Wat i have done so far is
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);
}

您可以尝试在索引时多次添加相同的字段，例如
you can try to add the same field multiple times while indexing like
