Even with prefix query, I do not get "ABCD02" or any "ABCD02..." back. BTW: EdgeNGramFilterFactory is used on the field we are getting the suggestions/spellchecks from. I think the problem is that there are a lot of different part numbers starting with "ABCD" and every part number has the same length. I showed only 4 in the example but there might be thousands.
Here are some full part number examples that might be in the index: ABCD1100000040 ABCD0000000000 ABCD9999999999 ABCD1000055500 ... I'm looking for a way to make Solr return distinct list of fixed length substrings of them, e.g. if "ABCD" is entered, I would need ABCD00 ABCD01 ABCD02 ABCD03 ... ABCD99 Then if user chose "ABCD42" from the suggestions, I would need ABCD4201 ABCD4202 ABCD4203 ... ABCD4299 and so on. I would be able to do some "post processing" if needed or adjust the schema or indexing process. But the key functionality I need from Solr is returning distinct set of those suggestions where only the last two characters change. All of the available combinations of those last two characters must be considered though. I need to show alpha-numerically sorted suggestions; the smallest value first.

Also, how are your queries fashioned? If you're doing a prefix query, everything that matches it should score the same. If you're only doing a prefix query, you might need to add a term for exact matches as well to get them to show up.
