### Install Recoll On Ubuntu / Linux Mint ###
|
||||
|
||||
Recoll is available in the Ubuntu repositories, However it is better to add Recoll repository and install the latest version.
|
||||
|
||||
Add Recoll repository using command:
|
||||
|
||||
sudo add-apt-repository ppa:recoll-backports/recoll-1.15-on
|
||||
|
||||
Update the package list with command:
|
||||
|
||||
sudo apt-get update
|
||||
|
||||
Now install Recoll using the following command.
|
||||
|
||||
sudo apt-get install recoll
|
||||
|
||||
For other distros, see the [download page][2] to download and install it from source.
|
||||
|
||||
### Launch Recoll ###
|
||||
|
||||
Recoll can be launched either from Dash or Menu.
|
||||
|
||||
|
||||
|
||||
At first launch, you’ll be asked to do indexing your whole home directory. This will take a while depending upon the size of your Home directory and no of files you have. Press the Start indexing now button.
|
||||
|
||||
|
||||
|
||||
Also you can adjust the indexing configuration and indexing schedule, if you want to more control of indexing. To do so, simply click on the Indexing configuration or Indexing schedule links. If you want to do it later, you can access these tools from the Preferences menu.
|
||||
|
||||
Once the indexing is done, you can start searching files/folders. The result will be displayed according to the exact relevancy and with a small snippet of the matched content.
|
||||
|
||||
### Configuration ###
|
||||
|
||||
As i noted above, you can adjust the Recoll indexing function if you want more control.
|
||||
|
||||
There are two configuration sections in the Recoll tool.
|
||||
|
||||
1. Index configuration
|
||||
|
||||
2. Index schedule
|
||||
|
||||
Let us see a short description of above sections.
|
||||
|
||||
**Index Configuration** is the section where you want to include directories or exclude the paths from indexing. By default Home directory will be included in the index. You can just remove and add some specific directory(s) for indexing.
|
||||
|
||||
|
||||
|
||||
Also you can define the web history queue and the max size of the web store.
|
||||
|
||||
**Index schedule** is the section where you want to define a schedule to automate batch indexing runs, or start real time indexing when you log in.
|
||||
|
||||
|
||||
|
||||
Recoll supports two indexing schedule:
|
||||
|
||||
**Cron Scheduling** – decides at what time indexing should run and installs the crontab entry.
|
||||
|
||||
|
||||
|
||||
As per the above screenshot, the recoll cron job will run on every day at 12 am. After setting up the cron job, click enable to make it active.
|
||||
|
||||
**Real time indexing start up** – decide if real time indexing will be started when you log in.
|
||||
|
||||
|
||||
|
||||
By enabling this option, the recoll daemon will start on every reboot. Be mindful that this settings is applicable only for default index.
|
||||
|
||||
### Basic Search ###
|
||||
|
||||
Hope you knew enough about Recoll now. It is time to search some files/folders. The beauty of this application is it finds keywords inside documents as well as file names.
|
||||
|
||||
In the Recoll interface, enter the search term(query) on the top right search box and click Search button.
|
||||
|
||||
|
||||
|
||||
As you see in the above picture, the result will be displayed with exact relevant contents, a small snippet and preview option of the matched contents. You can directly open the searched file by clicking on the Open button or preview it before opening using the Preview button.
|
||||
|
||||
Also you can filter the results according to their categories such as “media”, “message”, “other”, “presentation”, “spreadsheet” and “text” etc. Moreover you can choose the search results that should match “Any term”, “All terms”, “File name” or “Query language”.
|
||||
|
||||
### Advanced Search ###
|
||||
|
||||
Click the Advanced Search icon on the Menu bar or go to **Tools -> Advanced Search**. This will open a new window. From here you’ll be able to search more advanced with clauses. For example i am searching for files that contains matches keyword as “hp” and filename as “storage”.
|
||||
|
||||
|
||||
|
||||
This will find and displays the files that contains the keyword as “hp” and file name as “storage”.
|
||||
|
||||
|
||||
|
||||
### Unity Desktop And Website Integration ###
|
||||
|
||||
This application supports desktop and website integration. If you want to integrate this with your Ubuntu Unity desktop, install **recoll-lens** with following command.
|
||||
|
||||
sudo apt-get install recoll-lens
|
||||
|
||||
Please note that the Lens is limited to showing at most 20 results. If you want get more than 20 search results, edit **rclsearch.py**, change the “**if actual_results >= 20:**” line.
|
||||
|
||||
If you are using Firefox browser and want to search the website history that you visit everyday, you can use [this firefox extension][3]. This extension works together with Recoll to index the websites that you visit all day. After installing this extension, enable it from the Web history tab of Recoll Index Configuration.
|
||||
|
||||
|
||||
|
||||
All Linux distributions has built-in search function in their file manager to find files/folders as easy as possible. For those who aren’t not happy with the built-in search functionality and looking for an advanced text search tool, then Recoll is a worth trying tool. For me, this tool is lot easier and more powerful for basic and as well as advanced searches.
|
||||
|
||||
Cheers!

Recoll:针对Unix和Linux桌面的文本搜索工具
|
||||
===
|
||||
[Recoll][1]是一个Unix和Linux桌面的文本搜索工具。Recoll可以既可以搜索文件名还可以搜索文件内的关键字。
|
||||
|
||||
Recoll可以为你做到以下这些。
|
||||
|
||||
- 它可以搜索任何格式的文件
|
||||
- 支持通配符
|
||||
- 可以搜索依据文件的作者、类型、大小和格式等条件进行搜索
|
||||
- 可以搜索存储在任何位置的文件，例如文件、归档文件、邮件附件等
|
||||
- 支持桌面和网站集成
|
||||
- 火狐插件可以支持索引web页的历史
|
||||
- 点击一下搜索结果就可以在本地编辑器内打开或者显示预览
|
||||
- 它是自由开源的，在GPL许可下发布
|
||||
|
||||
###在Ubuntu/Linux Mint上安装Recoll
|
||||
|
||||
Recoll在Ubuntu仓库里可以找到。然而，最好添加Recoll的仓库以便安装最新版本。
|
||||
|
||||
使用命令添加Recoll仓库：
|
||||
|
||||
sudo add-apt-repository
|
||||
|
||||
使用命令更新软件源：
|
||||
|
||||
sudo apt-get update
|
||||
|
||||
现在就可以使用下面的命令安装Recoll。
|
||||
|
||||
sudo apt-get install recoll
|
||||
|
||||
对于其它的发行版，可以去[下载页面][2]下载源代码并编译安装。
|
||||
|
||||
###启动Recoll
|
||||
|
||||
Recoll可以从Dash或者菜单中启动。
|
||||
|
||||
|
||||
|
||||
第一次启动时，你需要索引整个家目录。依据你家目录里储存的东西的多少这将需要多少不等的时间。按下**Start indexing now**按钮开始索引。
|
||||
|
||||
|
||||
|
||||
假如你想更多的自定义索引，可以调整索引配置和索引计划。要做到这一点，只需要点击一下**Indexing configuration**或者**Indexing schedule**链接。假如你要稍后再去配置，你可以在首选项菜单里配置这些选项。
|
||||
|
||||
一旦索引完成，你就可以搜索文件/文件夹了。结果将根据相关性和匹配的一小部分内容而展现。
|
||||
|
||||
###配置
|
||||
|
||||
正如上面我提到的，假如你想更多的控制索引的细节，你可以调节Recoll的索引功能。
|
||||
在Recoll的工具中有两个配置项
|
||||
|
||||
1.索引配置
|
||||
2.索引计划
|
||||
|
||||
让我们来看一下上面这两个的简短描述。
|
||||
|
||||
**索引配置**可以让你索引时决定包含哪些目录以及排除哪些目录。默认情况下索引时将包含整个家目录。你可以在这儿从索引中添加或移除目录。
|
||||
|
||||
|
||||
|
||||
你也可以决定web历史记录索引以及储存web页面的最大容量。
|
||||
|
||||
**index schedule**则是可以让制定一个计划以便于进行自动索引或者当你登陆如系统后就进行实时索引。
|
||||
|
||||
|
||||
|
||||
Recoll支持两种索引计划：
|
||||
|
||||
**Cron任务** - 决定什么时候开始运行以及写入Crontab键值。
|
||||
|
||||
|
||||
|
||||
以上这个屏幕截图中，Recoll的cron任务会在每天上午12点的时候执行。设置完cron任务后，点击enable键激活它就可以咯。
|
||||
|
||||
**开启实时索引** - 决定是否当你登陆入系统后进行实时索引。
|
||||
|
||||
|
||||
|
||||
激活这一选项，recoll的守护程序都会随系统启动。要注意的是这一选项只有在默认索引设置的情况下才可用。
|
||||
|
||||
###基本搜索
|
||||
|
||||
现在你已经对Recoll了解的足够多了。是时候去搜索一下文件或者文件夹了。这个应用的美妙之处就在于它既可以搜索文件名还可以搜索文件内的关键词。
|
||||
|
||||
在Recoll的用户界面中，在顶部右边的搜索栏中键入要搜索的关键字，然后点击Search按钮。
|
||||
|
||||
|
||||
|
||||
如你在上图所见，精确相关的内容将会显示还能预览到一小部分内容。你可以点击Open按钮直接打开搜索到的文件，或者在打开它之前使用预览按钮预览它。
|
||||
|
||||
你还可以过滤搜索结果，使用分类例如，媒体、消息、其它、演示文档、电子表格或者文本等。更重要的是，你还可以通过选择使搜索结果匹配任一项、全部项、文件名或者语言等来过滤搜索结果。
|
||||
|
||||
###高级搜索
|
||||
|
||||
点击菜单栏中的高级搜索图标或者前往**Tools->Advanced Search**。这将打开一个新的对话窗口。在这儿你可以附加更多的限制条件来进行搜索。例如我可以搜索文件内容里含有关键字“hp”以及文件名为“storage”的文件。
|
||||
|
||||
|
||||
|
||||
这将找到并显示文件内含有关键字“hp”且文件名为“storage”的文件。
|
||||
|
||||
|
||||
|
||||
###Unity桌面以及网站集成
|
||||
|
||||
这个应用支持桌面集成以及网站集成。假如你要把它集成到你的Ubuntu的Unity桌面中去，你可以用下面的命令安装**recoll-lens**。
|
||||
|
||||
sudo apt-get install recoll-lens
|
||||
|
||||
请注意，lens限制显示结果最多显示20条。假如你要显示更多数目的搜索结果，编辑**rclsearch.py**，修改“**if actual_results >= 20:**”这一行就可以咯。
|
||||
|
||||
假如你使用火狐浏览器，要去搜索你每天访问的浏览历史，你可以使用这个[火狐扩展][3]。这个火狐扩展可以和Recoll一起工作去索引你全天浏览的网站。在安装完这个扩展之后，在Recoll的索引配置中从web历史标签页中激活它就可以咯。
|
||||
|
||||
|
||||
|
||||
所有的Linux都在他们的文件管理器中内建了搜索功能以便于尽可能容易的搜索文件/文件夹。对于那些不喜欢内置的搜索的功能以及想要寻找更加高级的文本搜索工具的人来说，Recoll是个值得一试的工具。对于我来说，这真是个容易使用且功能强大的工具，对基本搜索如此，对高级搜索也是如此.
|
||||
|
||||
欢呼吧！
