I am a developer. Website is made on Wordpress by me. I am using custom integration (PHP scripts), not Wordpress plugin, to index custom post types. With each post, there are post meta indexed, such as:
title: Sea View Apartment in Biyada
content: [long text description goes here]
… (more fields)
I want to search like “Available 3 bedroom apartment under $800000”. Everything is ok, but how to search for price < 800000? Or can I just replace “under” with “<” symbol?
