How to solve the problem with Zend Lucene when creating an index?

Question

Zend Framework

Hello!
Wrote a website on October CMS + Laravel 5. Development is carried out on Open Server. Fighting machine on Ubuntu 14.10
For search, I used a wrapper over Zend Lucene https://github.com/nqxcode/laravel-lucene-search
The problem is that under Windows the indexing works in full, and the last deployment on Ubuntu, although it says that everything worked without problems, files with indexes are created, but 1 file with the sti extension is not created.
As a result, the search on the combat vehicle does not work.
Help advice please.
