Details:

Varnam has knowledge about lot of words. This idea proposes a method to use
these words and provide suggestions for other input systems. Basically, in
Varnam, the API call will be something like,

```c
varnam_get_suggestions (handle, "भारत");
```

This will fetch all the suggestions which has the given prefix. 

`varnam_get_suggestions` needs to keep track of the previous words and use
[n-gram](http://en.wikipedia.org/wiki/N-gram) based dataset to filter the
results. This should also learn the words back into the word corpus that
varnam is using. Filtering suggestions won't be just a prefix search, but it
will have knowledge about how text can be written in the target language and
provide smart filtering. Searching in a large corpus and providing real-time
suggestions makes this a challenging task. 

Once this is implemented in `libvarnam`, it can be used in the ibus-engine.

* Complexity: Advanced
* Knowledge required: C
