Synonyms are exclusive to the index table engine, supporting any custom post type and media attachment contents.
To use synonyms, the index table engine is required. Before you start with this tutorial, I highly suggest reading up the introduction to the index table.
The synonyms interface can be accessed on the Index Table submenu, under the Synonyms panel.
To add a new synonym, simply click on the +Add new button on the top of the panel. Enter the desired original word and the synonyms (max. 15), then hit the Save button.
To edit a synonym row, click on the Edit button on the right side of the row. The same editor will appear, that is used to add a new synonym.
To delete an individual synonym row, click on the Delete button. Alternatively, you can delete all synonyms by clicking the Delete all button on the top right side of the panel.
Export and import feature lets you export the content of the synonyms database, and import it on a different installation, or for simply back-up purposes.
Click on the Export button on the top right side of the panel.
A pop-up window will open. Click the Generate New button, to generate a new export file.
After a short time, a link will appear. Click on it to save the export file on your computer.
The exported file is a .txt file, please do not change the file type.
To import previously exported synonyms, click on the Import button on the top right side of the panel.
A pop-up window will open. Click on the upload button to upload the import file via the media library uploader, and select it.
After selecting the file, click the Import button. After a short time, the success message should appear, with the number of imported items.
