Good day all! I'm new to the Koha system - we're using it for our charter high school library. We've only had it installed for about 2 months and I'm now responsible for maintenance and enhancements. In our library, we need the ability for users (high school students) to be able to search for books using a lexile number range. For example: Find all the books that have a lexile number between 100 and 200. I don't see this as an option anywhere in the advanced search so I was going to try and create the option. Here are my questions: 1. Has anyone done this yet? 2. I'm assuming there has to be something in the Zebra indexing system that allows this - being ignorant of Zebra, can anyone assist?
