<p>The following doesn't work, but something like this is what I'm looking for.</p>

<pre><code>select *
from Products
where Description like (@SearchedDescription + %)
</code></pre>

<p>SSRS uses the @ operator in-front of a parameter to simulate an 'in', and I'm not finding a way to match up a string to a list of strings.</p>

Have you tried to do:
```
select * from Products where Description like (@SearchedDescription + '%')
```
(Putting single quotes around the % sign?)
