next search based on last search result

Consider two scenarios:

1. You wanted to find all lines that calls a function collect with the input arguments of apple but not orange. Normally, one would come up with a rather complicated regex that looks similar to this (this is not even correct; could not get my head around something like this as a single regex) collect.*[(apple)][^(orange)]. Solution: first search all lines that contain collect, then in those lines search for lines that contain apple, then in these lines, continue searching for lines that does not have orange. Basically, it is grep 'collect' file | grep 'apple' | grep -v 'orange' using grep.
2. Similar task as above. Let's search through the whole project for files that has lines like that above, but also only for files than mention orchard. You would use grep -rl 'orchard' /path/to/project/ | grep 'collect' | grep 'apple' | grep -v 'orange' using grep and it's -l switch along with xargs.

Basically, it is the | tunnels, but being able to perform grep's -v and -l switches as well, easily, right from within almighty atom. I could not find how to do that from within atom vanilla, or using any of the existing packages. Am I missing something, or is this actually a feature to consider?

Selection can act as a pipe as in, make a search, select results (bunch of cmd+d), then make a new search in selection. Multiple selection work great for that. However search does not support negative query.

With complex query usually i'm either OK with doing manual pruning, or if it's a data collection task then OK with using dedicated tool. Grep looks like the right tool for your task.

While it is not a one shot search, I would not call it "complex" query. I think you are suggesting that this is not an editor task. I think I agree, thought Unite for Vim dues that happily. (I believe there are Emacs packages that dues this too).

With search on selection, can we search into the selected files when each selection is a filename? Haven't tried, but I doubt so.

com·plex adjective 1. consisting of many different and connected parts. synonyms: compound, composite, multiplex

Possibly the proper solution for atom is a community package too ? A lot of discussion about package development happens on the https://discuss.atom.io/ board.

Maybe what I was trying to say is that in grep the unit of work is a line. This make it easy to make query such as :

• lines that contain two word, with gap between word, and with possibly inversed order word.
• lines that does not contain a word.

Find & replace works on consecutive characters. This make it easy to do:

• Multiple result on a single line
• A single result containing multiple lines.

And while ultimately a line is made up of consecutive character, the different representation make different kind of query very easy / hard to express.
