1. Since JMeter 3.1 you should be using JSR223 Test Elements and Groovy language for scripting therefore consider switching to Groovy
2. Don't refer JMeter Functions and/or Variables in scripts directly as it might cause unexpected behavior or script malfunction. Either use "Parameters" tab or go for code-based equivalents
3. Beanshell print() function basically writes the value to STDOUT, if you want to write the value to a file you should do it differently.

Assuming all above you should be using something like:

new File("/path/to/your/file.csv") << vars.get("search")
