I'm using Magento and want to disable the enter key on the search bar. My code is below for search bar:

```
<form id="search_mini_form" action="<?php echo $catalogSearchHelper->getResultUrl() ?>" method="get">
    <div class="input-box">
        <label for="search"><?php echo $this->__('Search:') ?></label>
        <input id="search" type="search" name="<?php echo $catalogSearchHelper->getQueryParamName() ?>" value="<?php echo $catalogSearchHelper->getEscapedQueryText() ?>" class="input-text required-entry" maxlength="<?php echo $catalogSearchHelper->getMaxQueryLength();?>" placeholder="<?php echo $this->quoteEscape($this->__('Search entire store here...')) ?>" />
        <button type="submit" title="<?php echo $this->quoteEscape($this->__('Search')) ?>" class="button search-button"><span><span><?php echo $this->__('Search') ?></span></span></button>
    </div>

    <div id="search_autocomplete" class="search-autocomplete"></div>
    <script type="text/javascript">
    //<![CDATA[
        var searchForm = new Varien.searchForm('search_mini_form', 'search', '');
        searchForm.initAutocomplete('<?php echo $catalogSearchHelper->getSuggestUrl() ?>', 'search_autocomplete');
    //]]>
    </script>
</form>

```

Any ideas on how I can do this?
