Two replacement words directly following each other did not
work as expected because each expects a space at the
beginning/end while there was only one space available.
Also forbit composing a word after a space was added in the
end by a previous replacement.
Make sure all special symbols are removed during normalization already.
Those won't be interpreted in any way because they are unlikely to be
searched for.
The new format combines compound splitting and abbreviation.
It also allows to restrict rules to additional conditions
(like language or region). This latter ability is not used
yet.
This adds precomputation of abbreviated terms for names and removes
abbreviation of terms in the query. Basic import works but still
needs some thorough testing as well as speed improvements during
import.
New dependency for python library datrie.
