Apache Solr for TYPO3 is a widely used Search Solution on TYPO3 websites. It has been around for 10 years and it's time to look on the learnings the development team at dkd has made. We will look at how the setup to create innovation was made. We will also look at how a matured project needs to find a balance between maintenance and adoption of changes in the technologies involved TYPO3 CMS and Apache Solr Server. Last but not least we will look at the current status and the perspectives for 2020. Olivier Dobberkau is founder and CEO of dkd Internet Service GmbH in Frankfurt, Germany. He is President of the TYPO3 Association. He has over 20 years of experience in new media and the internet. His expertise lies in the areas of project management, infrastructure, and large organizations.

11. 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!

12. 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!

13. 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
