Ignore a folder in search results - intellij-idea

Question

I'm searching for a string and getting matches in a source folder, and a build folder (file in source gets copied to build during build).
I do not need the build folder result.
Vim has wildignore which helps filter out results.
Is there something similar in intelij?

Answer 1

Mark your build folder as excluded:
File > Project Structure > Modules > Sources > Mark as Excluded (red icon)
You can also just right click on your folder and select Mark Directory As > Excluded.
Excluded folders (shown as rootExcluded) are ones that IntelliJ IDEA "partially ignores". Very limited coding assistance is provided for files in excluded folders. Classes contained in excluded folders don't appear in code completion suggestion lists, references to such classes are shown in the editor as unresolved. When searching, IntelliJ IDEA doesn't look in excluded folders, etc.

Note: See the answer by Nader Hadji Ghanbari for another approach using Scopes.

Answer 2

Short Answer
By defining a Scope when searching, you can include/exclude arbitrary files/folders from that scope.
Detailed Answer
One way to achieve your requirement (excluding files and folders from a search) is to define a custom scope. This is specifically useful because sometimes you just want to exclude a folder from your search and not from the whole project.
Follow these steps:
Edit -> Find -> Find in path or press Ctrl+Shift+F.
Choose Custom in the Scope section and then choose <unknown scope>
Now click on the + button to add a new local custom scope
Give the scope a name and save it.
Now you can include and exclude directories from this scope. You can first add everything by choosing the include recursively and then exclude one by one by choosing exclude or exclude recursively.
Note that you can even include or exclude libraries your project is dependent on.
When searching you can choose the effective scope by in Scope section in Find in Path dialog.
More info
You can check the JetBrains docs on Scopes for more info. Scopes can be used not only when searching but also in a bunch of other use cases in IntelliJ IDEA.
Patterns
You can use Patterns to define a scope which makes them even more powerful and future proof.
using patterns is another way to exclude files and folders. For instance
file:src/main/java//*&&!file:src/main/java/my//* will exclude all files in my folder.

Answer 3

In Intellij 15, to exclude a folder just do this:
in the Project window, select the folder then right click and choose "Mark Directory As" > "Excluded"

Answer 4

IntelliJ IDEA 2021.3.3 (Ultimate Edition)
In my case, all the generated files in .tox and _build kept showing up in my Find results. It may be a blunt instrument but I added these two folder types to the Preferences -> Editor -> File Types -> Ignored Files and Folders: .tox, _build. For whatever reason, adding _build will not be accepted as part of the ignored set.
Caveat, you will not see these files and folders in your Project navigator. However, it’s a small price to pay for not having them show up consistently in my search results.

Answer 5

A number of answers work well for older versions of IntelliJ, but in 2020.2, and possibly other recent versions, I keep seeing excluded folders in my search results. In my case: node_modules.
I found something that does work, though. For javascript projects, at least. There might be something similar available for other languages.
First, of course, exclude the directory from your project.
Hopefully this works, but if it doesn't, and you're using Javascript, continue:
Go to Settings -> Languages & Frameworks -> Javascript -> Libraries
There, uncheck all the directories you don't want included in your search.
Whether this is a good idea remains to be seen; IntelliJ doesn't merely exclude them from your search, but from all its code parsing, which means it might not recognise imports from that directory either. For me it seems to work fine at the moment, but I give no guarantees. Try it, but remember how to revert this.
It's an ugly work around. IntelliJ clearly needs a better way to exclude directories from searches.

Answer 6

As some have mentioned, simply setting a folder to 'Excluded' doesn't work in many versions. A combination of the following does for me:
Set the offending folder to 'Excluded' as suggested.
Use the pre-defined Scope 'Project Files'

Excluding files and folders from projects

Mark a file as plain text
In the Project tool window, select the desired file.
From the context menu of the selection, choose Mark as plain text:
Exclude files and folders by name patterns
In the Settings/Preferences dialog Ctrl+Alt+S, click Directories .
In the Exclude files field, type the masks that define the names of files and folders to be excluded, for example, *.min.js or lib. Use semicolons as separators.
If the name of a file matches any of these patterns, the file is treated as excluded.
If the name of a folder matches a pattern, all the files in this folder and in its subfolders are excluded.

Answer 8

This one the only thing that works for me on IntelliJ 2022.3.1, even when marking directory as excluded didn't work (it only change the icon as red, but still shows up).
File > Preferences > Editor > Ignored Files and Folders
I can ignore the generated bla.html with this.

If you are searching for usages, open the "Find Usages Settings..." , by default Ctrl+Alt+Shift+F7, to narrow down the scope from "All files" to "Project files".
