我不太了解我通过Elasticsearch获得的结果。我的研究结果似乎不一致。
通过此搜索
{"query": {
"multi_match" : {
"query" : "tarif new",
"fields" : [ "titles^3", "texts" ]
}
}}
我有2个结果：
"titles": "Tarif New 208 (07/2019), Tarif New 208, Tarif New 208 , FREDERIC, f.mignon@lab360.be, , ",
和
"titles": "Tarif Traveller (07/2019), Traveller, Tarif New Traveller, , , , ",
但使用此搜索：
{
"query": {
"multi_match" : {
"query" : "tarif",
"fields" : [ "titles^3", "texts" ]
}
}
}
我只有1个结果：
"titles": "Tarif Traveller (07/2019), Traveller, Tarif New Traveller, , , , ",
我的索引是由Elasticsearch .NET使用
创建的var indexDescriptor = new CreateIndexDescriptor(indexName)
.Mappings(ms => ms
.Map<EsContent>(m => m.AutoMap()
.Properties(p => p
.Text(t => t
.Name(n => n.Titles)
.Fields(ff => ff
.Keyword(k => k
.Name("keyword")
.IgnoreAbove(256)
)
)
)
.Text(t => t
.Name(n => n.Texts)
.Fields(ff => ff
.Keyword(k => k
.Name("keyword")
.IgnoreAbove(256)
)
)
)
.Text(t => t
.Name(n => n.Tags)
.Fields(ff => ff
.Keyword(k => k
.Name("keyword")
.IgnoreAbove(256)
)
)
)
)
));
我真的不明白这些结果。当我用“ tarif”一词搜索时，为什么结果中没有出现“ Price New 208（07/2019）”？

我不明白为什么如果我用“ Tarif”一词搜索时找不到文档ID：5816，而如果我用“ tarif new”搜索时看起来很好。 如果我通过单词“ new”和单词“ 208”进行搜索，它也会出现在结果中。
我也尝试使用此映射，但结果相同：

我想这意味着“ tarif”一词的索引正确。
