[Tracker] sparql function

[Putinei Ionut <putineiionut gmail com>]

Hello,

I have to implement a search on tracker sparql over a column holding how a word is pronounced.
It is for asian characters.For example i have this string "äçä" that is pronounced "LeJianTi".
When i do search i am refering to a operator "like" is have to search to a valib group......so the first character must always be upper case.
Search for "Len" should return the result but the search after "eJian" should not return nothing.

What i am thinking:
-write search function in sqlite engine for this job but i don't know how to get that function to sparql layer.

Does sparql have some interface to implement for a new funtion?

If you guys have another idea please share it.


Thank you,
Ionut
