First, use the [Keyword Statistics] function in [Data Exploration] to calculate the number of times a keyword is mentioned, and store the data results to the field [Keyword Statistics]. Click to see the instructions of the [Keyword Statistics] feature
Then click [Filter] under [Quality Monitoring] to filter out data with less than 2 occurrences of the keyword. The procedure is shown in the following image. After filtering, click [Batch Deletion] in the upper right corner.
