Smart Search replaces the native WordPress search engine using the Microsoft BING Search API. Results are displayed according to your current theme.
Providing a search engine is a very complex subject if you aim to handle topics like relevance, semantics, performance and so on.
Smart Search enhances the WordPress search engine by querying Microsoft BING and its Search API. The search query is performed in the context of your website url, just like you would type the following search query on BING:
site:http://www.yourblog.com find this or that
URLs from the BING result set are converted by Smart Search to WordPress post IDs, thus the display process is the same your theme implements for regular searches.
You can also choose to cache the search engine's results for a defined period of time, which basically means that your site will load a little bit faster if the same search query is used.
Easy, simple and fast! If this is your way and fits your needs, you could consider Smart Search Pro and its extended features.
Note: your blog content must be indexed by BING in order to see the matching result set. Go here to submit yuor site to BING. Feel free to give leave a review here. To get in touch with me you can drop me an email.
