Use single non-alphabet characters as separators when indexing search terms

Text separated by any single non-numeric, non-alphabetic character should be indexed a second time using those characters as separators. This will permit much more flexible and realistic search results, since users mentally separate out characters such as my.project and important_document_name.

A suitable programming-related use case is when indexing methods. To index

dbo.tblTransactions(SomeDataType var)

should produce

dbo.tblTransactions(SomeDataType
dbl
tblTransactions
SomeDataType
var)
var
