<title
>Help Index</title>

<note
><para
>At the time of writing, for most installations of &kde; the entire search engine function in &khelpcenter; is disabled, and settings made in this &kcontrol; module will have no effect. We hope to have it back in a future release.</para
></note>

<para
>&kde; comes with a lot of documentation for applications and components. While it is possible to just browse the manuals until you find that piece of information you're looking for, this may be a very time-consuming task. To make this easier for you, &kde; offers fulltext search using a program called <application
>ht://dig</application
>. It works quite similar to search engines on the web, in fact some search engines you now might even use it. Just click on the <guilabel
>Search</guilabel
> tab in the &khelpcenter;, enter the word you are looking for, click <guibutton
>Search</guibutton
> and enjoy!</para>

<para
>However, to make use of this feature, <application
>ht://dig</application
> has to be installed on your system and &kde; has to be configured to make us of it. This control module tries to help you doing the latter. If you haven't installed <application
>ht://dig</application
> and it wasn't shipped with your operating system you have to get ht://dig yourself. Have a look at <ulink url="http://www.htdig.org"
>the ht://dig homepage</ulink
> on how to download and install it.</para>

<para
>When you first start, you are in display mode only. To modify your settings, click on <guibutton
>Administrator Mode</guibutton
>. If you are logged in as <systemitem class="username"
>root</systemitem
>, you will go straight to the change dialogue. If not, &kde; will ask for a superuser password.</para>
<sect2 id="help-index-use"

<title
>Use</title
> 

<para
>There are two important things to tell &kde; so it can make use of the fulltext search engine:</para>

<itemizedlist>
<listitem
><para
>where to find the <application
>ht://dig</application
> programs KDE uses for fulltext search</para
></listitem>
<listitem
><para
>where to search</para
></listitem>
</itemizedlist>

<sect3 id="help-index-use-progs">

<title
>The <application
>ht://dig</application
> Programs</title>

<para
>There are three programs &kde; needs that come with <application
>ht://dig</application
>: <command
>htdig</command
>, <command
>htsearch</command
> and <command
>htmerge</command
>. For each program you have to provide the full path including the program name, for example: <filename class="directory"
>/usr/bin/htdig</filename
>.</para
> 

<para
>Where exactly these programs are installed depends on your operating system or your distribution. However, there are some good guesses you might want to try:</para>

<itemizedlist>

<listitem
><para
><command
>htdig</command
> and <command
>htmerge</command
> are often found in <filename class="directory"
>/usr/bin/</filename
> or in something like <filename class="directory"
>/usr/local/www/htdig/bin/</filename
>.</para
></listitem>

<listitem
><para
>the <command
>htsearch</command
> command is often found in a sub folder called <filename class="directory"
>cgi-bin</filename
>, for example <filename class="directory"
>/usr/local/httpd/cgi-bin/</filename
>.</para>

</listitem>
</itemizedlist>

<tip
><para
>To find out where for example <command
>htdig</command
> is installed you can always type <command
>whereis htdig</command
> on the console. <command
>whereis</command
> will look for the specified command in the standard execution path folders. However, folders like <filename class="directory"
>cgi-bin</filename
> are often not in the standard execution path.</para
></tip>

<sect3 id="help-index-use-scope">
<title
>Scope and Search Paths</title>

<para
>In this section you can choose which help resources should be indexed, &ie; made available to the search engine.</para>

<para
>In the <guilabel
>Scope</guilabel
> frame you can select some typical resources you want to be indexed, &ie; the &kde; help files, and the information offered by the <command
>man</command
> and <command
>info</command
> commands. Note that some of those may still be disabled, which means that support for them has not been added yet.</para>

<para
>Maybe you have additional files you want to access using the &khelpcenter; fulltext search feature. For example, you might have an <acronym
>HTML</acronym
> reference installed in <filename
>/home/jdoe/docs/selfhtml</filename
>. By adding this path to the list of additional search paths you make this documentation available to &khelpcenter;'s fulltext search, too. Just click on the <guibutton
>Add</guibutton
> button and a file dialogue will ask you for an additional search folder. Select <filename class="directory"
>/home/jdoe/docs/selfhtml</filename
> and click <guibutton
>OK</guibutton
>. To remove an additional search path, just select it and click <guibutton
>Delete</guibutton
>.</para>

<important
><para
>Your changes to the scope and additional search paths will not take effect if you don't click on the <guibutton
>Build index</guibutton
> button.</para
