Google Search plugin for MT

I posted the questions about how to use Googel Search in the Beta forum at 6A. They replied so quickly. I tried and it works.

Here is the official answer for Google Search, almost same as V3.2, Setting Up Google Enabled Entries.
Follow the guide above, you can add Google search results related to your post title into your individual archives.

I thought about the usability of Google Search plugin yesterday night.
The Google Account and license key entitle you to 1,000 automated queries per day.
This is very important limitation for Google Search.
Check Google API site.

For example, if you have a blog with three years history and over 1,000 entries. You also have the Google Search Results into your individual archives template. What happen when you post a new entry or rebuild the who site. I think the error will be coming. The Google may disable your API.

Even you only have very small amount of entries, say 100 posts. If the Page View of your site over 1,000 per day, and you use the dynamic publishing, the error will come again.

So I think only two situations the Google Search plugin may be useful.
1) Use dynamic publishing, the PV is less than 1,000.
2) Use static publishing, the post is less then 1,000.

The truth is Blog is growing up. More and more entry will be added. So the Google Search is a useless plugin.
