Hi

It is not so easy.

The best approach is to use dual tokenisation which will ba available in 3.2, or not to tokenise the property.
Then use Alfresco FTS to do a pattern search "A*"

Thanks for your reply. By the way we have changed the analyzer for some of our properties, they are not tokenized or transformed for instance (from "A B C" to "A_B_C", or anything else which is not a stop word), and now we could search and find what we needed to.
