New version 1.2 released!
This plugin analyzes the referrer search engines URI and extract the serach terms making a statistics to be showed as a cloud in your blog. Read behind for information on problem with AdSense solved in version 1.1 and for new features of version 1.2.
To add the cloud in the sidebar, just put in this PHP call:
<? search_cloud_words(); ?>
It produces a list of term links that run a query within the word press search system. The terms font size will be proportional to the number of seraches made with them. Some parameters will be added (this is a call for ideas!) in the next release.
Major search engines and blocked words are included, but help me to add more leaving a comment.
Attention: this plugin serializes the statistics on the file system without using the database, so it may lead to concurrency problem in high traffic sites. A future release will be improved, but for little blog it work very well, and it's very fast.
The plugin add a link to my site under the term list, you can remove it if you feel better without it.

Version 1.2 news
In this new version I've added a configuration page under Plugins/Search Cloud. Now you can control the blocked word list, the hit number threshold to show/hide the keywords (minimun hits, always or mean), if display the keywords hit. Thank you to brucalipto for the great help!
Added a "clean up" function in the option page to clean the list (not to erase... only to clean).
An improvement was made to stop msnbot in followin the keyword links.
AdSense problems
My blog runs AdSense and some days after the installation of this plugin, the ads start to disappear. I think the all the search words printed in the page was considered spam. Now the link with the keywords are generated with Javascript, so they are "less" readable from the search engines, but still present in the page. I hope this can solve the problem.
