Acknowledgments

Although I would go the same way if I could go back in time, the time during the writing of this book was not easy for my family. The ones that suffered from this the most were my wife, Agnes, and my two great kids—son Philip and daughter Susanna. Without their patience and understanding, writing this book wouldn't have been possible. I would also like to thank my and Agnes' parents for their support and help.

I would like to thank all the people involved in creating, developing, and maintaining Lucene and Solr projects for their work and passion. Without them, this book wouldn't have been written.

Once again, thank you.
