Too busy to set up and host a Yioop search engine yourself? provides a variety of Yioop services. Besides hosting Yioop indexes, these can involve help with regard to installing, customizing, upgrading, or tuning Yioop. They can also involve paying for new features to be added to the next iteration of Yioop or for customizations not to be included in the main code base.

The Install Guides explain how to get Yioop to work in some common settings. The documentation page has information about the requirements of and installation procedure for Yioop.


Before upgrading, make sure to back up your data. Then download the latest version of Yioop and unzip it to the location you would like. Set the Search Engine Work Directory by the same method and to the same value as your old Yioop Installation. See the Installation section above for links to instructions on this, if you have forgotten how you did this. Knowing the old Work Directory location, should allow Yioop to complete the upgrade process.

Git Repository / Contributing Code

The Yioop git repository allows anonymous read-only access. If you would like to contribute to Yioop, just do a clone of the most recent code, make your changes, do a pull, and make a patch. For example, to clone the repository, assuming you have the git version control software installed, just type:

git clone

The Yioop Coding Guidelines explain the form your code should be in when making a patch as well as how to create patches. You can create/update an issue in the Yioop issue tracker describing what your patch solves and upload your patch. To contribute localizations, you can use the GUI interface in your own copy of Yioop to enter in your localizations. Next locate in the locale folder of your Yioop work directory the locale tag of the language you added translations for. Within this folder is a configure.ini file, just make an issue in the issue tracker and upload this file there.
