? 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
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
随时根据手机所在位置<em>定位</em>,显示具体城市和街道
google map 定位搜索
可以实现google map的<em>定位</em>, <em>搜索</em>, 模式选择的功能, 以及点击<em>搜索</em>到的气泡, 弹出位置信息框

sift特征--关键点搜索定位
前面介绍了如何生成高斯图像金字塔,并计算了每组图像的高斯差分图像。现在介绍如何进行关键点<em>搜索</em>与<em>定位</em>(都在灰度图上搞的)。一、极值点计算   关键点是由DOG空间的局部极值点组成的。为了寻找DoG函数的极值点,每一个像素点要和它所有的相邻点比较,看其是否比它的图像域和尺度域的相邻点大或者小。每一幅高斯差分图像中的一个像素点,要和它同尺度的8个相邻点和上下相邻尺度对应的9×2个点共26个点比较,以确保
