下面的Elastic Query不为我的应用程序返回任何结果
"query" : {
"bool" : {
"must" : [
{
"simple_query_string" : {
"query" : "IN-123456",
"fields" : [
"field1.auto^1.0",
"field2.auto^1.0"
],
"flags" : -1,
"default_operator" : "AND",
"analyze_wildcard" : false,
"auto_generate_synonyms_phrase_query" : true,
"fuzzy_prefix_length" : 0,
"fuzzy_max_expansions" : 50,
"fuzzy_transpositions" : true,
"boost" : 1.0
}
}],
"adjust_pure_negative" : true,
"boost" : 1.0
}
}
}
请注意，我在 flex 数据源中存在带有与field2匹配的文本“IN-123456”的文档。
我可以搜索与“123456”相同的文档作为查询中的文本。
以下是使用的索引

最佳答案
检查您的映射。下面的查询工作正常。
POST v_upload_branch/_doc
{
"branch_name":"IN-123456",
"branch_head":"Chennai",
}
GET v_upload_branch/_search
{
"query" : {
"bool" : {
"must" : [
{
"simple_query_string" : {
"query" : "IN-123456",
"fields" : [
"branch_head^1.0",
"branch_name^1.0"
],
"flags" : -1,
"default_operator" : "AND",
"analyze_wildcard" : false,
"auto_generate_synonyms_phrase_query" : true,
"fuzzy_prefix_length" : 0,
"fuzzy_max_expansions" : 50,
"fuzzy_transpositions" : true,
"boost" : 1.0
}
}],
"adjust_pure_negative" : true,
"boost" : 1.0
}
}
}

关于elasticsearch - 当查询包含 “IN”前缀时，为什么 Elasticsearch 不返回结果？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/59260485/
