&lt;br /&gt;&lt;span style=&quot;color: rgb(128, 0, 0);&quot;&gt;Find entries by searching for (partial) words or symbols. Enable &lt;b&gt;&amp;quot;search full text&amp;quot;&lt;/b&gt; to search not only in the &amp;quot;concept field&amp;quot; but also in the description / definition field.

Are you &lt;b&gt;new to the TeX Filter or to TeX?&lt;/b&gt; Then you might want to read step by step through the different categories, starting with category &lt;b&gt;&amp;quot;01 Getting started&amp;quot;&lt;/b&gt;.&lt;/span&gt;&lt;br /&gt;
&lt;p style=&quot;font-size: 8pt;&quot;&gt;&lt;u&gt;Test your TeX-Syntax:&lt;/u&gt;&lt;br /&gt;
&lt;a href=&quot;http://moodle.org/filter/tex/texdebug.php&quot; target=&quot;_new&quot;&gt;Test your syntax interactively here&lt;/a&gt;. This Link is also available on each moodle site itself: &amp;quot;&lt;i&gt;../filter/tex/texdebug.php&lt;/i&gt;&amp;quot;&lt;br /&gt;&lt;/p&gt;
&lt;p style=&quot;font-size: 8pt;&quot;&gt;&lt;u&gt;About the TeX filter:&lt;/u&gt;&lt;br /&gt;The TeX filter for Moodle has been implemented by &lt;a href=&quot;mailto:fiedorow@math.ohio-state.edu&quot;&gt;Zbigniew Fiedorow&lt;/a&gt;. It is based on &lt;a href=&quot;http://www.forkosh.com&quot; target=&quot;_new&quot;&gt;John Forkosh's mimeTeX&lt;/a&gt; 1.40.&lt;br /&gt;&lt;u&gt;Contacts:&lt;/u&gt;&lt;br /&gt;For suggestions, critics, help etc. about &lt;i&gt;this reference&lt;/i&gt; visit the &lt;a href=&quot;http://emathpool.net&quot;&gt;eMathPool&lt;/a&gt; website or &lt;a href=&quot;mailto:andreas.leiser@emathpool.net&quot;&gt;send me&lt;/a&gt; an email.&lt;br /&gt;For any other information about the TeX filter or about moodle, please visit the &lt;a href=&quot;http://moodle.org&quot;&gt;moodle&lt;/a&gt; website.&lt;br /&gt;
