On the evening of December 6th, the AVForums search facility was upgraded. It was a minor release fixing a few issues.
The one which will affect AVForums members most will be the ability to correctly search for terms containing the minus sign. Previously the search engine used the minus sign to denote 'and do not search for', the same as Google, except it didn't differentiate between that and the use of a minus sign within a search term as a normal character - like in dog-and-duck.
To illustrate, do a Google search for sony ps3 and then sony -ps3 and note the difference.
Now the AVForums internal search system works the same way.
An immediate example is if you search for wi-fi, now returns what we would expect.
