Can Tsearch be used to return substring matches?

i.e

Text to search: Hi my email addres is psql-mail(at)freeuk(dot)com

Query "psql" would match the email address?

Query "mail" would also match?

Query "reeu" would also match?

Or is tsearch not suitable for this type of query? should i use FTI
instead?

Thanks.
