Hi Dmitry

Ignore word endings in Greenstone means use stemming - all words are
stemmed to their root, and then a search on the root is carried out.
I guess that librarian and library must stem to different roots.

MGPP recently had word truncation added to its searching. This is
available in the 2.52 release. You need to specify it in the search with
a *, like libr*. (Note this is not available with MG).

It is not possible to switch indexers (other than MG and MGPP) without
programming (C++ and perl). We are in the process of adding Lucene in as
an indexer but it is not completed yet.
