<indexterm zone="isearch"><primary>search</primary><secondary>incremental</secondary></indexterm>

<para>
The conventional search with <menuchoice><guimenu>Edit</guimenu>
<guimenuitem>Find</guimenuitem></menuchoice> requires you to specify the full
search term before starting. Most of the time, it is much faster to search
incrementally. If you click into the edit field labeled
<guilabel>ISearch</guilabel> in the toolbar, the search is performed as you
type. You will find that often the desired term is already found after typing
in 3 or 4 letters.
</para>

</sect2> <!-- isearch -->


<sect2 id="grep">
<title>Grep</title>
<indexterm zone="grep"><primary>search</primary><secondary>in files</secondary></indexterm>

<para>
Both search mechanisms described above are restricted to searching within one
source file. An additional tool which allows you to search through a (possibly
large) number of files is available through the
<guimenuitem>Search in Files...</guimenuitem> item in the
<guimenu>Edit</guimenu> menu. It is basically a frontend for the
&grep;(1) program.
</para>

<para>
In the dialog, you can specify which files are searched. There is a number of
wildcard patterns available in a combobox. In this way, you can easily
restrict the find mechanism to header files. Furthermore, you specify a
directory where the search is started. If you check the
<guibutton>Recursive</guibutton> box, the search iterates through all
directories in the hierarchy below this one.
</para>

<para>
The search term is in general a regular expression following POSIX syntax.
For example, you can use the term <literal>"\&lt;K.*"</literal> if you want to
find all words which begin with the letter K. The following characters
are interpreted in a special way:
</para>

<informaltable>
<tgroup cols="2">

<row><entry>

</entry><entry>

</entry></row>
<row><entry>
  <literal>{n,}</literal>
</entry><entry>

</entry></row>
<row><entry>
  <literal>{,n}</literal>
</entry><entry>
  The preceding item matches less than n times
</entry></row>
<row><entry>
  <literal>{n,m}</literal>
</entry><entry>
  The preceding item matches at least <literal>n</literal> times but less
than <literal>m</literal> times
</entry></row>

</tbody>
</tgroup>
</informaltable>

<para>
Backreferences to bracketed subexpressions are also available by the notation
<literal>\n</literal>.
</para>

<para>
For C++ programmers, as special bonus there are some search templates
available for typical patterns. These allow you to search for example
all calls of member functions of a certain object.
</para>

<para>
Once you start the search by clicking on the <guibutton>Search</guibutton>
button, it will be performed by an external, asynchronous process. All found
items will appear in the view called <guilabel>Grep</guilabel>. You can then
jump to the found items by clicking on them. Note that grep scans the files
as they stored in the file system. If you have modified versions of them in
your editor, you may get some mismatches in the line number, or some found
items will be invalid. You can avoid this by saving all files beforehand.
