Add Search on My Website
I think many people work in this way and I guess the reason is we have been trained to by Google! The first search engine, Yahoo, originally had a page full of categories. Then along came the minimalist Google and a new verb was invented. People expect to be able to "Google" everything - we don't have time for menu systems.
So the obvious answer to the question, Should I add search on my website is: YES!
I have used Zoom search on all of my websites (the licence covers as many websites as you create) for several years.

A noticeable feature is the appearance of icons next to files to indicate the filetype - which means that Zoom Search will not only index normal web pages but also PDFs, PowerPoint and Word Documents - and even Flash.

You also get an idea of the other options from the Menu on the left. The settings for each of your sites can be saved in a configuration file.

Finally, Zoom Search can provide you with comprehensive charts and reports on the search activity on your website - very useful for refining your niche keywords research. Click on the image below.

Why you shouldn't use free Google Custom Search?
If you want to you can add a free search function from Google - but there are downsides:
advertisements appear on the results page - these diminish your brand
clicks on advertisements open in the same window - in other words, they leave your website - you have just provided direct links to your competitors. You do NOT have a choice in this - it is explicitly stated in Google's terms that AdSense links open in the same window.
lack of control over how the results appear
not as professional, in my opinion
You can earn a few cents per click from AdSense but for most businesses this is insignificant to the value of the potential business that has just gone to their competitors.
