The second AutoComplete instance does not enable queryMatchSubset so each typed letter results in a new request to the server.

<h1>Subset Matching</h1>
<div class="exampleIntro">
<p>This example demonstrates AutoComplete's <code>queryMatchSubset</code> property. The first instance of AutoComplete has <code>queryMatchSubset</code> enabled for maximum cache performance such that as you type, the query is searched within previously cached results. For best results, the DataSource should return a complete set of results when a single letter is queried such that subset matching will also return a complete set of results.</p>
<p>The second AutoComplete instance does not enable <code>queryMatchSubset</code>
so each typed letter results in a new request to the server.</p>
<p>Note the custom CSS that is needed for stacking AutoComplete instances.</p>
</div>
<!--BEGIN SOURCE CODE FOR EXAMPLE -->
<div id="autocomplete_examples">
<p><strong>Note:</strong> The flat-file database accessed here has a limited number of terms; for best results, type one-letter at at time and let the AutoComplete instance return — if you type a full, highly-specifc phrase (such as your name) you'll probably get no results from the small dataset.</p>
