Lucene搜索的过滤结果 [英] Filtering results of Lucene search

问题描述

让我解释一下我的问题.我正在使用Lucene在asp.net网页中搜索并显示结果.当我搜索时，Lucene会显示与我的搜索相关的所有记录.例如，我有5000条名称为John的记录.如果我输入John，它将显示所有这5000条记录.我想基于其他一些属性来限制这5000条记录.我有四个属性，分别是名字，姓氏，DOB和ID.在这5000条记录中，我希望它仅显示用户输入的DOB记录.这意味着只显示1998年5月12日拥有DOB的john的记录.这样会将结果限制在50条左右.完成此操作后，我想搜索具有相同ID的所有字段，然后显示这些记录.最后，我将获得具有给定DOB和相同ID的John记录.

Let me explain my problem. I am using Lucene to search and display the results in asp.net web page. When I am searching, the Lucene is displaying all the records associated with my search. For Example I have 5000 records with name John. If I type John it is displaying all this 5000 records. I want to restrict this 5000 records based on some other attribute. I have four attributes namely First Name, Last Name, DOB and ID. Out those 5000 records I want it to display only the ones with the inputted DOB by the user. This means just display the records of john who have DOB as 5/12/1998. This will restrict the result to around 50 records. Once I am done with that I want to search all the fields who have same ID and then display those records. In the end I will have records of John with given DOB and same ID.

注意:通过DOB进行过滤是出于安全目的.

Note: Filtering by DOB is for security purpose.

以下是我的搜索代码.

The following is my Code for search.

        List<SearchResults> Searchresults = new List<SearchResults>();


        string indexFileLocation = @"C:\o";
        Lucene.Net.Store.Directory dir =     Lucene.Net.Store.FSDirectory.GetDirectory(indexFileLocation);

        string[] searchfields = new string[] { "fname", "lname", "dob", "id"};
        IndexSearcher indexSearcher = new IndexSearcher(dir);

        var hits = indexSearcher.Search(QueryMaker(searchString, searchfields));

        for (int i = 0; i < hits.Length(); i++)
        {
            SearchResults result = new SearchResults();
            result.fname = hits.Doc(i).GetField("fname").StringValue();
            result.lname = hits.Doc(i).GetField("lname").StringValue();
            result.dob = hits.Doc(i).GetField("dob").StringValue();
            result.id = hits.Doc(i).GetField("id").StringValue();
            Searchresults.Add(result);

        }

推荐答案

我讨厌这样做.但是我找到了答案.

I hate to do this. But I found the answer.

它

Filter fil= new QueryWrapperFilter(new TermQuery( new Term(field, "5/12/1998")));
var hits = indexSearcher.Search(QueryMaker(searchString, searchfields), fil);

您可以使用以上代码过滤结果.

You can filter the results with the above code.

我认为过滤查找值后可能无法返回.有人不同意吗?

I don't think its possible to go back after filtering for looking values. Anybody disagree?
