Looking back
• Started as a POC in 2009
• Codename “Act as Indexed Search”
• Client did not have enough funding
• Problem too big for not trying to solve it
• Indexed Search too limited & resource hungry
• Others we spoke too had the same “itch”
• We had an Idea!

Looking back
• We asked other TYPO3 agencies if they would
be willing to share development costs
• We found some and they all had projects
limited with current search feauture
• The Early Access Program was born
• Each Partner founded 4000 EUR and even
more
• Partners can be found on our Website!

What have we learned?
• Building TYPO3 extensions is not a part time
job, but many try and many fail
• Integration of external applications means
double the work
• People value Innovation less than maintenance
• Developers decide way different than managers
• Its all about the balance of interests

How does it continue?
• Apache Solr Server is continuously evolving
• Almost every year a new version
• TYPO3’s 18 month release cycle and 3 year
support (plus the 3 ELTS) means old versions live
very long
• Conflict!
• How can this be solved?
