Can I have multiple comparisons within a single criteria parameter? The Craft site shows an example using a single comparison

Building upon this example from that page:

craft.entries.width('&gt;= 100')

Can I do something similar but where 'width' is ALSO less than or equal to 200?

Conceptually:

craft.entries.width('&gt;= 100 &amp;&amp; &lt;= 200')
You can combine multiple criteria like so:

{% set entries = craft.entries.width('and, &gt;= 100, &lt;= 200') %}


but what you can't do is to combine multiple statements to build more complex criteria:

{% set entries = craft.entries.width('and, &gt;= 100, &lt;= 200' or '&gt;= 500') %}


in your case this wouldn't make much sense. But see my still unanswered question on this topic for another example: "Complex logic on a ElementCriteriaModel parameter?"
