Vim CommandT- like search for strings

Question

Is there a way in vim to search (grep/ack etc..) for strings in files in a similar fashion like one would do in CommandT?

So say that I invoke the search window. Possible matches for the string I wrote so far will start to show while I continue typing.

Answer 1

I don't think there is any native (as in :set findasyoutype) way to do exactly what you want.

But there's a plugin for that ! Well, at least three:

• LustyExplorer provides this feature through its :LustyBufferGrep command. It requires Vim to be compiled with Ruby support.
• CtrlP too, provides this feature through the line extension.
• You can also try FuzzyFinder which I've never used.

Answer 2

I don't know how it looks like in CommandT, but if you issue the command :set incsearch (or put it in your .vimrc), once you search as usual, using /, vim highlights the first found item.
