Thanks Jackson.
“search-everything” works perfectly!
Maybe bardo wanted a plugin like http://www.advancedcustomfields.com/add-ons/flexible-content-field/ ,but it is not free. (It seems a great plugin that worth the price 😉
I meet the same problem yet. I have tried such plugin as “custom-field-template” to guide users to input every necessary information. Like this:
_______________
| Book : _______|
| Author :______|
| Price :_______|
|_____________|
And then, I want to format the text above to HTML code and save as post-content, not “meta”, because it would be very easily searched by users.
