Create a small module for Typo3 CMS that incorporates [url removed, login to view] OpenSearch XML/RSS Search results into the Typo3 System and presents the results in within the framework.
1. Create Search Block that says "Search X Site X Internet" for searching the local site or the internet and using OpenSearch to provide the Results.
2. Create Module that ties into block that will present the search results to the user offering some extensibility such as search term highlighting or other nifty features.
Pretty simple block & module. Should only take half an hour for someone familiar with PHP & XML/RSS integration.
Please see [url removed, login to view] and our developer section for small guide and try searching to view XML output.
