Searching the blog answers

I tried a few searches without knowing if this platform was capable of the use of key words, phrases, etc. It picked words and phrases out of titles and the bodies of the blogs. now to see if I can pull up more than one blog at a time by being sure to use a key word or phrase I know to be in more than one entry. If anyone has other descriptors they would like me to test for searching a blog, please let me know.

For My Information: Searching the blog archives

Does anyone know if there is a way to search on Blogger by key word, phrases or some other method rather than date? If not, is there a platform that will support these types of searches for entries on the blog? I have heard of WordPress, but have not looked into it yet.
