I want to put a search box into a Base form so that I can search for specific records
Hello,
There is no such thing in Base as a search box. You can, however, search for information using control(s), a filter table and SQL. This allows searching for data within fields in records in a table. There are many posts and samples in this forum dealing with filtering. Here are a few related posts:

display specific record in a form
Within these answers are links to further information (more detailed explanation of filtering) and various samples. There are many ways to do filtering and really depends upon what specific end result you are looking for.

There is also another method - using the Form Filter. For that see my answer in this post → How to find specific words in a field query
