Each time I get terms not related to the term I am searching on.
For instance, I was searching on the term okra a short while ago.
I did find some instances of okra, but it also returned posts that did not have the word okra included.
The closes thing I found was an 'ok' as if used in the word look.
I was actually searching to find if anyone had used a product called Okra Pepsin E3 from Standard Process, but figured searching on the word okra would cast a broad net.
