+### Excluding files from venv
+
+By default, the find function in IntelliJ is not scoped and will include all files in the monorepo, including all the libraries installed as part of a connector's virtual environment. This huge volume of files makes indexing and search very slow. You can ignore files from the connectors' virtual environment with the following steps:
+
+1. Open the project structure using `cmd-;`
+2. Navigate to the "Project Settings / Modules" section in the right-side of the menu
+3. Select the top level `airbyte` module so the change is applied to all submodules
+4. Add the following filter to the `Exclude files` option: `connectors/**/.venv`
+5. Press OK to confirm your options.
