Searches forward for <em class="parameter"><code>str</code></em>. Any match is returned by setting
<em class="parameter"><code>match_start</code></em> to the first character of the match and <em class="parameter"><code>match_end</code></em> to the
first character after the match. The search will not continue past
<em class="parameter"><code>limit</code></em>. Note that a search is a linear or O(n) operation, so you
may wish to use <em class="parameter"><code>limit</code></em> to avoid locking up your UI on large
buffers.
</p>
<p>
If the <span class="type">GTK_SOURCE_SEARCH_VISIBLE_ONLY</span> flag is present, the match may
have invisible text interspersed in <em class="parameter"><code>str</code></em>. i.e. <em class="parameter"><code>str</code></em> will be a
possibly-noncontiguous subsequence of the matched range. similarly,
if you specify <span class="type">GTK_SOURCE_SEARCH_TEXT_ONLY</span>, the match may have
pixbufs or child widgets mixed inside the matched range. If these
flags are not given, the match must be exact; the special 0xFFFC
character in <em class="parameter"><code>str</code></em> will match embedded pixbufs or child widgets.
If you specify the <span class="type">GTK_SOURCE_SEARCH_CASE_INSENSITIVE</span> flag, the text will
be matched regardless of what case it is in.
