I often want to search for instances of something but I do not care about where it is found.
Case 1: Extracting data.
Delete-search and keep-search take care of this need for a single file.
They do not work on multiple files though :-(
Case 2: Finding unique instances of something.
For example, what are all of the unique instances of "import com.foo.bar." in my java sources?
(Sometimes I also do this with "list matches only" as well when I don't want the rest of the line with a match).
To do this, I have to:
FiF for "import com.foo.bar." in *.java.
In results,
Align Columns
select all
copy
File->New
Paste
Sort
Using column select, remove the line/col prefix and the "File..." lines.
Sort again, removing duplicate.
All pretty tedious - much of it because Search returns more information than I need.
