I am also very confused at the use case for the Suggester component. With collate on, it will try to combine random words together not the actual phrases that are there.
I get better mileage out of EDGE grams and tokenize on whitespace... Left to right... Since that is how most people think. However, I would like Suggester to work as follows: Index: Chris Smith Tony Dawson Chris Leaf Daddy Golucky Query: 1. "Chris" it returns "Chris Leaf" but not both Chris Smith and Chris Leaf. 2. I seem to get collated (take first work and combine with second word). SO I would see things like "Smith Leaf".... Very strange and not what we expect. These are formal names. When I use Ngrams.... I can index: C Ch Chr Chri Chris S Sm Smi Smit Smith Thus if I search on "Smi" it will match Chris Smith and also Chris Leaf. Exactly what I want.
