What does id and weight infer in the below union of keyset.h about marisa-trie HOT 4 CLOSED

The `weight' is used as an input to marisa::Trie::build().
The `id' is used as an output, where `id' is an ID, as you mentioned.

If you specify weights, the order of a predictive_search() may vary.
But it is just a hint to boost the search performance.
The order of a search result is undefined.
Also note that the `weight' is overwritten with `id' in marisa::Trie::build().

Regards,

Thanks for the reply.
I want to use weight for a purpose of storing an extra info for every
string may be frequency of every string .so can I do that.if I do that does
Id value get invalid.
Suppose if I'm not using weight ,I query for a string to marisa true,say I
get 10 results .and now if I build marisa trie without weight and then I
query for the same thing,I will get all the 10 entries right .?

Weights are not available after marisa::Trie::build(), because they are used 
and then discarded. If you want to keep weights associated with keys, like 
values in a key-value store, please store the weights into an extra array. You 
can get key IDs from the keyset.

If you don't give weights, marisa-trie uses the default weight (1.0). So, the 
result does not change. But please note that the order may change.
