<h1>Help for SQL expressions</h1>
<h2>Description</h2>
<p>The &laquo;SQL expression&raquo; is added to WHERE clause of
view feed query. You can match on most fields of ttrss_entries table
and even use subselect to query additional information. This
functionality is considered to be advanced and requires basic
understanding of SQL.</p>
<h2>Examples</h2>
<pre>unread = true</pre>
Matches all unread articles
<pre>title like '%Linux%'</pre>
Matches all articles which mention Linux in the title. You get the idea.
<p>See the database schema included in the distribution package for gruesome
details.</p>
