The Yahoo BOSS plugin makes it easy to create a search engine in your WordPress install. Simply activate and configure and you’re off and running. This plugin does not replace the default search within WordPress.
<a href="http://developer.yahoo.com/wsregapp/" rel="nofollow ugc">Yahoo Search BOSS</a> (Build your Own Search Service) allows you to create a search engine using Yahoo technologies via a REST API. Currently, only web content search (images and news coming soon) is supported. You will need to get your own <a href="http://developer.yahoo.com/wsregapp/" rel="nofollow ugc">BOSS application ID</a> to create your search engine. Use of this plugin subjects you to the <a href="http://info.yahoo.com/legal/us/yahoo/search/bosstos/bosstos-2317.html" rel="nofollow ugc">BOSS API Terms of Use</a>. Please read carefully.
In order for your search engine to function correctly, you need to define where you want both the search form and the search results to show. This is done with simple shortcodes that you need to add to a page or pages.
To create the search form add [boss_search_form] to a page.
To define where you want your search results use [boss_search_results]. Nothing will show if a query hasn’t been performed.
The page contents would be the following if you wanted a search form followed by the search results.
[boss_search_form]
[boss_search_results]
Use [pw_search] to combine both shortcodes.
Alternatively, there are numerous template functions available if you prefer to use those over shortcodes.
That is all you need to do to create your custom search engine.
<h3>Administration</h3>
You need to modify a few options for the plugin to work correctly.
Yahoo App ID: add your <a href="http://developer.yahoo.com/wsregapp/" rel="nofollow ugc">Yahoo BOSS application ID</a> here. This option is required.
Results per Page: use to configure how many search results you want to show on each page. Default is 10.
Format: the format of the search results. This would be useful if you want to use with AJAX. Default is XML.
Domains to Search: add site urls here if you want to limit your search to certain sites (one per line).
<h3>Extending</h3>
Yahoo App ID can be overridden with a defined constant in wp-config.
<pre><code>define('YAHOO_APP_ID', 'your_app_id_goes_here');
</code></pre>
There are some filters available to use.
pw_boss_title – applied to the title of the search engine in the search form. Filter function arguments: title.
pw_boss_button – applied to the button to initiate the search in the search form. Filter function arguments: button text.
pw_boss_stylesheet – applied to the search engine stylesheet to provide your own custom stylesheet. Filter function arguments: default stylesheet.
pw_boss_result_info – modify the result meta information (1-10 of 201321 results for WordPress)

This is special plugin which helps your WordPress site to easily create sitewise XML sitemap and ping Google, Bing, Yahoo and Ask.com to index your WordPress site or blog. This plugin generates XML sitemap following sitemap.org Sitemap protocol to help search engines like Google, Yahoo, MSN to better understand and index your blog. The Sitemap protocol enables you to provide details about your pages to search engines, and we encourage its use.
The XML sitemap created using this plugin satisfies completely with Sitemap.org protocol which says
The Sitemap must:
*Begin with an opening tag and end with a closing tag. 
*Specify the namespace (protocol standard) within the tag. 
*Include a entry for each URL, as a parent XML tag. 
*Include a child entry for each parent tag. 
All other tags are optional. Support for these optional tags may vary among search engines. Refer to each search engine’s documentation for details. 
Also, all URLs in a Sitemap must be from a single host, such as www.example.com or store.example.com.
With such a sitemap, it’s much easier for the crawlers to see the complete structure of your site and retrieve it more efficiently. The plugin supports all kinds of WordPress generated pages as well as custom URLs. Additionally it notifies all major search engines every time you create a post about the new content.
It will do exactly what it’s supposed to do – providing a complete XML sitemap for Google, Yahoo, MSN, ASK and other search engines. It will not break your site, slow it down or annoy you. Guaranteed!
