When we change configuration in ezfind.ini, and add a new class with a boost, and updateindex, that is not considered.

#ezfind.ini
[IndexBoost]
Class[]
Class[user]=5.0

This is du to a case sensitive issue on ezsolrdoc::DocBoost property.
$this->docBoost have to be written this->DocBoost in ezsolrdoc.php to fix this issue.

I suggest a pull request : https://github.com/ezsystems/ezfind/pull/107
