? 求助lucene 搜索定位

使用lucene进行<em>搜索</em>时,由于分词器做了一次处理而无法<em>定位</em>到原文,请有知道的朋友告知下rn如:rn中共中央rn市场rn农贸rn社会文明rn基因rn工农rn电话rn传播rnrnrnrnrn我<em>搜索</em>关键字"电话",但是无法得到准确的行数.

datagridview搜索定位的问题！

我的一个winform程序里用了datagridview，通过一个文本框的textchange事件来选择datagridview的某一行，效果如下：[img=http://www.ntfybj.com/Edit/UploadFile/200910/20091012143020176.jpg][/img]rnrn我的datagridview里有一列“code”是隐藏的，textbox的textchange事件触发后，就是将textbox的text与datagridview的code列去对比的，如果相等了，则那行被selected，当时测试时效果是达到了，但是没想到真正用的时候遇到了如下问题：rnrn数据量大了之后，用户输入了正确的code，相应的行是被选中了，但是滚动条却没有自动滚动使被选中行跳到可以看到的地方，需要用户上下拖动滚动条去寻找。请高手帮助！rnrn相关代码如下：rn[code=C#]rn private void textBox9_TextChanged(object sender, EventArgs e)rn rn int i;rn for (i = 0; i < dataGridView1.RowCount; i++)rn rn if (dataGridView1.Rows[i].Cells[4].Value.ToString().Trim() == textBox9.Text.ToString().Trim())rn rn dataGridView1.Rows[i].Selected = true;rn rn elsern rn dataGridView1.Rows[i].Selected = false;rn rn rn rn[/code]

高德地图-定位+附近+搜索

最近在开发商城类的项目，需要用到地图<em>定位</em><em>搜索</em>等功能，这里整理了下发出来。 1：studio配置     文档上给的很清楚，这里简单写下：     gradle中添加jar： //高德地图部分 implementation 'com.amap.api:3dmap:5.0.0' implementation 'com.amap.api:location:3.3.0' ...

天地图API搜索。定位等

empty 地图API调用 .search{font-size:13px; border:1px solid #999999;} .ls{line-height:27px; padding-left:7px;} .prompt{display: none; font-size:13px; border:1px solid #999999;} .s

高德定位+poi搜索

先贴张图 不忙的时候自己研究了下可以实现上诉图片功能展示的实现。通过功能来分析，实现上述功能首先获取当前位置信息，这是先进行<em>定位</em>操做mLocationClient.startLocation();<em>定位</em>成功后调用onLocationChanged(AMapLocation amapLocation)方法，通过ampLocation实例可以获取当前<em>定位</em>点的信息，如地理 位置信息经纬度等。

SuperMapGIS 搜索定位

关键技术： SuperMapGIS

高德定位及poi搜索

集<em>定位</em>、周边<em>搜索</em>、关键词<em>搜索</em>、调用高德查询路线的个人测试高德demo一份，希望可以帮助到大家，以及后续自己可以查看（注：<em>定位</em>、poi都在同一activity中，我想这是你们想要的吧）

城市搜索定位
