Smart Search Engine

Descripcion

Bring a REAL search engine into your WordPress website in 5 minutes, for free!

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 and that in New York

Brief

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.
Search results come from Microsoft BING. This means semantics and relevance on board!!

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.

In order to use it, you must have a valid Windows Account key and you will need to activate at least the free subscription here or here

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.

FAQ

Why should I install this search goodness?
  • You don’t have to setup and mantain an indexing engine since Microsoft BING crawls your website for you
  • Keep in mind that a large percentage of users, first will scroll the page looking for a search input box – [Steve Krug]
  • It is not always easy to provide a lean navigation structure, especially when you have a deep content structure. An efficient search and find approach leads to more page views.
  • Sooner or later, users will think « Let me find it » or « Let me see if is here ». Allow them to do it well!
  • User experience is more pleasant if you can easily find what you need
  • A website with a good search engine gains reliability
Why BING and not something else?
  • BING is free up to 5,000 search queries per month
  • No credit card required
  • Other plans over this threshold are competitive too
  • BING is the most competitive one I’ve been able to find for this kind of API
  • BING search results are always satisfactory as well as those of Google

On top of that Smart Search is flexible enough for developers who want to use a different search engine provider.

Troubleshooting
  • Highlighter is broken in title or is breaking something else
    This issue is generally theme related.
    Let me guess, your theme’s search.php file has a function call that looks like this:

<h2 title=" »>

This happens because the_title() is not supposed to be used in HTML attributes. In this case the_title_attribute() should be used instead.
This is the correct usage:

<h2 title=" »>

Have a look at this post to deepen.

  • Results are always empty
  1. Check if your website is indexed by BING: go to http://bing.com and type the following
    site:mysite.com
    replace « mysite.com » with your domain.
    If you see some results you’re on the good way, otherwise let BING index your blog.
    Important Note: Taxonomy pages like /category/news, /tags/politics, /author/john etc. are not included in search results because they’re archives, not posts or pages. This is one of the core features of Smart Search Pro
  2. If you have any other search related plugin active, try to deactivate it in order to avoid unexpected conflicts.
