How to Build a Custom Search Engine

image

Custom Search is a great way to build a search engine that searches only the sites you want. This is useful if you find you’re trawling those sites—blogs, government sites, news sites, etc—on a regular basis and would rather search them all in one go.

Setting it up is pretty easy.

Go to Google’s Custom Search Engine page.

Click on the blue button:

Enter a name, and a brief description:

Enter some keywords relevant to your beat and the language you’re working in:

Select the first option in the next list (Only sites I select) – unless you want to include the web in your search, with the sites you select in the next window given priority:

Start typing in (or pasting) the names of the websites you want to include. Include http:// s ; it won’t work without.

Try a few test queries to see if you need to tweak. If you do, hit the browser’s back key and tweak:

When you’re happy, click Finish. (You can always add more sites later.)

You’ll then be sent to a page listing your search engine, and any others you choose to add. If you need to tweak, click on the control panel link; the homepage link will take you to the search box of the relevant engine.

Here’s a couple of custom search engines I’ve built as examples:

Tip(s)

It’s worth bookmarking this page, or even adding it to your iGoogle page if you have one.

  • Some websites don’t submit themselves to Google well. For mission critical searches, compare the results of your engine with those of the site’s own search. Sometimes Google does a better job, but sometimes it doesn’t.
  • Custom search works best a tool to use alongside RSS feeds. RSS is great for monitoring new stuff; custom search is great for looking up background or hunting other less time-sensitive stuff: names, projects, companies etc
