问题描述
使用 Apache Ignite .NET 2.3.0尝试使用 Linq 扩展 (Apache.Ignite.Linq) 进行搜索.
Using Apache Ignite .NET 2.3.0Trying to search using Linq extension (Apache.Ignite.Linq).
配置:
CacheConfiguration = new[]
{
new CacheConfiguration
{
QueryEntities = new []
{
new QueryEntity(typeof(string), typeof(SecuritiesItem))
{
Fields = new []
{
new QueryField { Name = "SearchString", FieldType = typeof(string)}
}
}
}
}
}
证券项目定义:
public class SecuritiesItem
{
/* all other fields */
public string ShortName { get; set; }
public string SearchString { get; set; }
}
SearchString 包含来自所有需要在搜索中使用的字段的合并数据.像这样:
SearchString contains merged data from all fields what need to be used in search. Like this:
Открытое акционерное общество " Рога и копыта"#☢#Systems 开放式股份公司#☢#ОАО"РиК"#☢#Ssys#☢#335468321#☢#bner#☢#ОАО "РиК"#☢#Systems Open Joint-Stock Company#☢#Открытое акционерноеобщество "Рога и копыта"#☢#Systems开放股份公司#☢#RU003572593#☢#1-22-22222-A
像这样搜索:
_securitiesCache
.AsCacheQueryable()
.Where(s => s.Value.SearchString.Contains(query))
// or .Where(s => s.Value.SearchString.ToLower().IndexOf(query) != -1)
.ToArray()
.Select(x => x.Value);
所以,如果我搜索打开" - 它会正常找到一切.但是,如果我搜索Откр",却找不到任何结果.
So, if i searching for "Open" - it find everithing normally. But if i searching for "Откр", no results found.
尝试按对象中的特定字段进行搜索,例如使用=="的 ShortName,结果相同.我应该将文本转换为特定的编码吗?
Trying to search by specific field in object, like ShortName using '==', same result. Should I convert the text into a specific encoding?
自我解决
这是邮递员的错.https://github.com/postmanlabs/postman-app-support/issues/2263 url 编码错误.
it's postman fault. https://github.com/postmanlabs/postman-app-support/issues/2263 bug in url encoding.
推荐答案
你能分享一个示例项目复制器吗?
Can you share a sample project-reproducer?
我更新了几个测试,它们在类似情况下运行良好.我没有更改编码或将文本转换为某种特定的编码,默认为 UTF-8.
I updated several tests and they work fine for a similar case. I did not change encoding or convert text into some specific encoding, it is in UTF-8 by default.
