Experimenting with it, need some heads up

[rvencu]

Hi, I have this problem at hand: given a text that is stripped of punctuation, basically a long series of words separated by spaces, I need to identify all items present in the trie, with the longest ones starting first.

As an example: if in trie I entered these terms
1 lorem ipsum dolor
2 lorem ipsum
3 dolor

If my text contains 'lorem ipsum dolor' I would like to confirm key 1 as a match and ignore 2 and 3. I need to extract this way all possible matched against the given trie.

I would appreciate a little heads up, maybe some relevant docs about how to manipulate these objects towards my goal.
