Inclusion of Function Description Information in Function Search

## User Story

As a user, I may not not the exact name of a flux function I am looking for, but I might be able to enter a key word that would exist in the description that might help me find it. I want to be able to search the description of the function, not just the name of the function so that I can more easily find what I am looking for.

## Acceptance Criteria

- When a user types a key word in the search box in the function selection list, the search results will include matches that have that keyword in the whole function description and not just the name

- The user will be shown a list of functions that match that search

- There is no requirement for any kind of search parameters at this time besides text
