Bug Report

Q	A
BC Break	no
Version	x.y.z

Summary

Unable to use FULLTEXT indexes when using SQL Server despite it supporting them.

Current behaviour

Currently, Doctrine only supports theses types of indexes in MySQL.

How to reproduce

1. Create a connection to an SQL Server.
2. Create a table using Doctrine
3. Add an index to the table via Doctrine with the fulltext flag

Expected behaviour

The index should be created using the SQL CREATE FULLTEXT INDEX.

Currently, it only uses the SQL CREATE INDEX.

I can't find information on microsoft.com about supported versions, but looks to be supported back to 2005 according to this site and others:
