You’re no doubt reading this article because you’re wondering what that SearchIndexer.exe process is all about, and why it’s chewing up a lot of RAM or CPU. Here’s the explanation you’re looking for, and how to deal with it.

毫无疑问，您阅读这篇文章是因为您想知道SearchIndexer.exe进程的目的是什么，以及为什么它占用大量RAM或CPU。 这是您要寻找的解释，以及如何处理。

那么这个过程是什么？ (So What Is This Process?)

SearchIndexer.exe is the Windows service that handles indexing of your files for Windows Search, which fuels the file search engine built into Windows that powers everything from the Start Menu search box to Windows Explorer, and even the Libraries feature.

SearchIndexer.exe是Windows服务，用于为Windows搜索处理文件索引，这为Windows内置的文件搜索引擎提供了动力，该引擎为从“开始”菜单搜索框到Windows资源管理器甚至是“库”功能的所有功能提供了支持。

You can see this for yourself by simply right-clicking on the process name in the Task Manager list, and then choosing Go to Service(s) from the menu.

只需右键单击“任务管理器”列表中的进程名称，然后从菜单中选择“转到服务”，就可以自己查看。

This will take you to the Services tab, where you can clearly see the Windows Search item selected in the list.

这将带您进入服务选项卡，您可以在其中清楚地看到列表中选择的Windows搜索项目。

If you take a look at the file properties, you can clearly see that this particular executable is the Indexer component for Windows Search—though the name probably gave that away already.

如果查看文件属性，则可以清楚地看到此特定的可执行文件是Windows Search的Indexer组件-尽管该名称可能已经将其删除了。

您如何停止此过程？ (How Do You Stop This Process?)

If you want to stop the service from running, you can open up Services through Control Panel, or type in services.msc into the Start Menu search box. Once you’re there, you can find Windows Search in the list and click the Stop button.

如果要停止运行服务，可以通过“控制面板”打开“服务”，或在“开始菜单”搜索框中键入services.msc 。 到达那里后，您可以在列表中找到Windows搜索，然后单击“停止”按钮。

We wouldn’t recommend disabling the service—you can simply uninstall it if you don’t want it.

我们不建议您禁用该服务-如果您不想要该服务，则可以直接将其卸载。

您如何卸载此服务？ (How Do You Uninstall This Service?)

We’re not recommending that you uninstall the Windows Search service, since it powers so much of the behind the scenes stuff in Windows 7, but if you want to remove it you can type windows features into the Control Panel search to pull up the Turn Windows features on or off screen. In here you can simply uncheck Windows Search and click the OK button. You’ll probably have to reboot your PC once that’s done.

我们不建议您卸载Windows搜索服务，因为它在Windows 7中提供了很多后台功能，但是如果要删除它，则可以在“控制面板”搜索中键入Windows功能以拉出Turn Windows功能在屏幕上显示或关闭。 在这里，您只需取消选中Windows搜索，然后单击确定按钮。 完成后，您可能必须重新启动PC。

如何使SearchIndexer使用更少的RAM或CPU？ (How Can I Make SearchIndexer Use Less RAM or CPU?)

Your best option is to cut down on the amount of data that you’re indexing—there’s usually no reason to index every single file on your drive. You’ll need to open up the Indexing Options through the Control Panel or Start Menu search box to make the changes.

最好的选择是减少索引的数据量—通常没有理由索引驱动器上的每个文件。 您需要通过“控制面板”或“开始菜单”搜索框打开“索引选项”以进行更改。

The first thing you should notice is the Pause button on this window, which can pause indexing for up to 15 minutes—useful if you’re trying to do something and Windows Search happens to be in overdrive mode, though it really shouldn’t since it only runs while your PC is idle.

您应该注意的第一件事是此窗口上的“暂停”按钮，该按钮最多可以将索引暂停15分钟-如果您要尝试执行某些操作并且Windows搜索碰巧处于高速模式下，则很有用，尽管实际上这不应该它仅在PC空闲时运行。

You’ll want to click the Modify button and then trim down the list of locations to just the ones you really need indexed—this can seriously improve the performance of your Start Menu search box as well.

您将要单击“修改”按钮，然后将位置列表缩小为您真正需要索引的位置，这也可以严重改善“开始菜单”搜索框的性能。

高级技巧：使Windows搜索仅索引文件名 (Advanced Tip: Make Windows Search Index Only Filenames)

If you click the Advanced button on the Indexing Options dialog, you’ll be able to access another set of settings—what we’re looking for here is the File Types tab on this dialog. Once you’re there, scroll down to some common formats like doc, docx, and other files, and you’ll see that they are configured to search the file contents by default.

如果单击“索引选项”对话框上的“高级”按钮，您将能够访问另一组设置-我们正在这里寻找的是此对话框上的“文件类型”选项卡。 到达该目录后，向下滚动到doc，docx和其他文件等一些常见格式，您会发现它们默认配置为搜索文件内容。

If you don’t actually search within the files and only care about the file names, you can trim down the index by changing this setting to Index Properties Only.

如果您实际上不在文件内搜索，而只关心文件名，则可以通过将此设置更改为“仅索引属性”来缩小索引。

结论：不应删除此过程 (Conclusion: This Process Shouldn’t Be Removed)

You really shouldn’t remove this process, but hopefully the lessons in this article will help you trim it down to size, and remember that you can always temporarily stop the service if you feel like it.

您确实不应该删除此过程，但希望本文中的课程可以帮助您缩小规模，并记住，随时可以随时停止该服务。
