Solr拼写检查器没有返回任何结果(Solr spellchecker not returning any results)

 我正在开发一个需要我第一次使用Solr的应用程序。 我设置了它，索引正确的数据，并按照我的意愿查询，但我似乎无法让拼写检查组件正常工作。 无论我查询什么，拼写检查器都不会返回任何建议。 我已经包含了solrconfig和schema.xml的相关部分。

 当我转到http://localhost:8983/solr/select/?q=query&spellcheck.build=true然后查看/ path / to / my / spell / index中生成的文件，有一个segments.gen和一个segments_1，两者都只包含几个字节的二进制数据。 然后，当我输入一个查询并将&spellcheck=true附加到查询字符串时，无论我的查询是什么，我都不会得到任何建议： 
 

<lst name="spellcheck">
  <lst name="suggestions"/>
</lst>

 

 知道这里发生了什么吗？ 

I am working on an application that requires me to use Solr for the first time. I got it set up, indexing the correct data, and querying as I would like it, but I cannot seem to get the spellcheck component working properly. No matter what I query, the spellchecker will not return any suggestions. I have included the relevant parts of my solrconfig and schema.xml.

When I go to http://localhost:8983/solr/select/?q=query&spellcheck.build=true then look at the files generated in /path/to/my/spell/index, there is a segments.gen and a segments_1, both of which contain only a few bytes of binary data. Then, when I enter a query and append &spellcheck=true to the query string, I get no suggestions, no matter my query:
 

<lst name="spellcheck">
  <lst name="suggestions"/>
</lst>

 

Any idea what is going on here?

最满意答案

 要处理鼠标悬停在非客户区域上，您可以在WndProc捕获WM_NCMOUSEHOVER 。 如文档中所述，悬停跟踪会在生成此消息时停止。 如果应用程序需要进一步跟踪鼠标悬停行为，则必须再次调用TrackMouseEvent 。 
 

 NonClientMouseHover事件实现 
 

 在下面的代码中，通过捕获WM_NCMOUSEHOVER引发了NonClientMouseHover 。 您可以像处理NonClientMouseHover任何其他事件一样处理NonClientMouseHover事件： 
 

using System;
using System.Runtime.InteropServices;
using System.Windows.Forms;

 

public class SampleForm : Form
{
    [DllImport("user32.dll")]
    private static extern int TrackMouseEvent(ref TRACK_MOUSE_EVENT lpEventTrack);
    [StructLayout(LayoutKind.Sequential)]
    private struct TRACK_MOUSE_EVENT {
        public uint cbSize;
        public uint dwFlags;
        public IntPtr hwndTrack;
        public uint dwHoverTime;
        public static readonly TRACK_MOUSE_EVENT Empty;
    }
    private TRACK_MOUSE_EVENT track = TRACK_MOUSE_EVENT.Empty;
    const int WM_NCMOUSEMOVE = 0xA0;
    const int WM_NCMOUSEHOVER = 0x2A0;
    const int TME_HOVER = 0x1;
    const int TME_NONCLIENT = 0x10;
    public event EventHandler NonClientMouseHover;
    protected override void WndProc(ref Message m)
    {
        base.WndProc(ref m);
        if (m.Msg == WM_NCMOUSEMOVE) {
            track.hwndTrack = this.Handle;
            track.cbSize = (uint)Marshal.SizeOf(track);
            track.dwFlags = TME_HOVER | TME_NONCLIENT;
            track.dwHoverTime = 500;
            TrackMouseEvent(ref track);
        }
        if (m.Msg == WM_NCMOUSEHOVER) {
            var handler = NonClientMouseHover;
            if (handler != null)
                NonClientMouseHover(this, EventArgs.Empty);
        }
    }
}

 

 例 
 

 根据您的问题，您似乎对该事件感兴趣的是最小化的mdi子窗口。 该事件还会针对最小化的mdi子窗体进行提升，因此如果出于任何原因想要在鼠标悬停最小化的mdi子标题栏时执行某些操作，则可以检查if(((Form)sender).WindowState== FormWindowState.Minimized) 。 另外((Form)sender).Text是引发事件的表单的文本。 
 

public partial class Form1 : Form
{
    ToolTip toolTip1 = new ToolTip();
    public Form1()
    {
        //InitializeComponent();
        this.Text = "Form1";
        this.IsMdiContainer = true;
        var f1 = new SampleForm() { Text = "Some Form", MdiParent = this };
        f1.NonClientMouseHover += child_NonClientMouseHover;
        f1.Show();
        var f2 = new SampleForm() { Text = "Some Other Form", MdiParent = this };
        f2.NonClientMouseHover += child_NonClientMouseHover;
        f2.Show();
    }
    void child_NonClientMouseHover(object sender, EventArgs e)
    {
        var f = (Form)sender;
        var p = f.PointToClient(f.Parent.PointToScreen(f.Location));
        p.Offset(0, -24);
        toolTip1.Show(f.Text, f, p, 2000);
    }
    protected override void OnFormClosed(FormClosedEventArgs e)
    {
        toolTip1.Dispose();
        base.OnFormClosed(e);
    }
}

 

 在此处输入图像描述 
 

 注意：感谢鲍勃 在这里发帖。 处理WM_NCMOUSEHOVER的初始代码已经从那里开始，并使用了一些更改并删除了一些部分。 

To handle a mouse hover over non-client area, you can trap WM_NCMOUSEHOVER in WndProc. As mentioned in documentations hover tracking stops when this message is generated. The application must call TrackMouseEvent again if it requires further tracking of mouse hover behavior. 
 

NonClientMouseHover Event Implementation
 

In below code, a NonClientMouseHover has been raised by trapping WM_NCMOUSEHOVER. You can handle NonClientMouseHover event like any other events of the form:
 

using System;
using System.Runtime.InteropServices;
using System.Windows.Forms;

 

public class SampleForm : Form
{
    [DllImport("user32.dll")]
    private static extern int TrackMouseEvent(ref TRACK_MOUSE_EVENT lpEventTrack);
    [StructLayout(LayoutKind.Sequential)]
    private struct TRACK_MOUSE_EVENT {
        public uint cbSize;
        public uint dwFlags;
        public IntPtr hwndTrack;
        public uint dwHoverTime;
        public static readonly TRACK_MOUSE_EVENT Empty;
    }
    private TRACK_MOUSE_EVENT track = TRACK_MOUSE_EVENT.Empty;
    const int WM_NCMOUSEMOVE = 0xA0;
    const int WM_NCMOUSEHOVER = 0x2A0;
    const int TME_HOVER = 0x1;
    const int TME_NONCLIENT = 0x10;
    public event EventHandler NonClientMouseHover;
    protected override void WndProc(ref Message m)
    {
        base.WndProc(ref m);
        if (m.Msg == WM_NCMOUSEMOVE) {
            track.hwndTrack = this.Handle;
            track.cbSize = (uint)Marshal.SizeOf(track);
            track.dwFlags = TME_HOVER | TME_NONCLIENT;
            track.dwHoverTime = 500;
            TrackMouseEvent(ref track);
        }
        if (m.Msg == WM_NCMOUSEHOVER) {
            var handler = NonClientMouseHover;
            if (handler != null)
                NonClientMouseHover(this, EventArgs.Empty);
        }
    }
}

 

Example 
 

Based on your question it seems you are interested to the event for a minimized mdi child window. The event also raises for a minimized mdi child form, so if for any reason you want to do something when the mouse hover title bar of a minimized mdi child, you can check if(((Form)sender).WindowState== FormWindowState.Minimized). Also ((Form)sender).Text is text of the form which raised the event. 
 

public partial class Form1 : Form
{
    ToolTip toolTip1 = new ToolTip();
    public Form1()
    {
        //InitializeComponent();
        this.Text = "Form1";
        this.IsMdiContainer = true;
        var f1 = new SampleForm() { Text = "Some Form", MdiParent = this };
        f1.NonClientMouseHover += child_NonClientMouseHover;
        f1.Show();
        var f2 = new SampleForm() { Text = "Some Other Form", MdiParent = this };
        f2.NonClientMouseHover += child_NonClientMouseHover;
        f2.Show();
    }
    void child_NonClientMouseHover(object sender, EventArgs e)
    {
        var f = (Form)sender;
        var p = f.PointToClient(f.Parent.PointToScreen(f.Location));
        p.Offset(0, -24);
        toolTip1.Show(f.Text, f, p, 2000);
    }
    protected override void OnFormClosed(FormClosedEventArgs e)
    {
        toolTip1.Dispose();
        base.OnFormClosed(e);
    }
}

Note: Thanks to Bob for his post here. The initial code for handling WM_NCMOUSEHOVER has taken from there and made working with some changes and removing some parts.
