Java but not java field input question

I am looking to have a feature where I have an entry field that, when you put certain inputs into the field, it brings you to certain pages.

Example: [query field] - site visitor enters "elephants"> hit enter> the site navigates them to the designated page for the input "elephants"

I learned how to do this feature in javascript, but I would need to upgrade to a premium service to use javascript in squarespace code blocks.

FROM SQUARESPACE: " On all plans, code blocks support plain text, HTML, Markdown, and CSS code surrounded by (style) tags. "

Question: Is there any way to code the feature I'm describing without upgrading my plan to use javascript?

TIA, I hope this was specific enough.

Perhaps you mean JavaScript? JavaScript is supported on Business Plans or above. Java is not supported.

Indeed Paul. I edited my op for clarity. Thanks for the help.
