I’m looking for an existing semi-decent software that can highlight multiple search terms simultaneously, using different colors, and show the count of each matching search term. I also need an easy way to apply the same keywords to different texts.
EDIT
To explain with an example, this does more or less what I need:

I put this together quickly because a friend of mine needed the functionality under time pressure. I am quite tempted to build on this, but I don’t want to reinvent the wheel. Such tool seems to be a pretty common need to me, like my friend I too often find myself wanting to do multi-keyword searches. I believe something must already exist out there I’m just unable to find it. I don’t want to reinvent the wheel, if there is such existing software, I am ok with throwing away my work so far and use what exists. If there is no such software, then I’ll be happy to continue hacking at this example above, I just really don’t want to foolishly reinvent the wheel.
I’d say with Vim Multiple Search script this is nearly done, except for counting. But this SO question tackles counting already.
If Vim is not your cup of tea, then I’d say Notepad++ (excerpt added from my comment above):
It certainly can highlight different tokens in different colors (you can configure colors as you see fit), I don’t know about counting. The difference might be in usage – IIRC Notepad++ hightlights on keypress / click on token – so you may need to find it first.
