I'm a mod here at HW and came across your post. There are a couple methods to searching for past posts:
1. Click on "Search' (next to 'Chat') and type in the key word(s) you are looking for. This search seems to mainly render findings based off the subject of the post only.
2. You can search for specific information from post contents by typing key word(s) and the following into Google: site:healingwell.com "search keyword here"
I hope that helps... Good luck!
