The keywords list show only top 500 keywords?

The count of keywords is not only 500,but the Piwik’s keywords list show only top 500 keywords.How can i see more??? via API ???

After the top 500 elements, Piwik automatically groups pages, keywords, websites, etc. under the label “Others”; How can I force Piwik to not limit the data?
