On another site, I want to pass a search string to my blog(i.e: http://www.myblog.com/?search=teststring and retrieve some content like this:
<title>blah blah</title>
<summary>blah blah blah</summary>
<link>http://www.myblog.com/post1</link>
I don't know if this is already available in wordpress. If I have to manually code this for myself, can you suggest where should I start? (I'm familiar with php and mysql, just new to wordpress)
Thank you.
