Increasing Limit of Site Search Keywords

By default Piwik shows only 500 Keywords for SITE SEARCH KEYWORDS.
i.e. keywords internally searched on website itself.

How can we increase this limit to say 3000 keywords?


Maybe this faq entry helps: After the top 500 or top 1000 rows, Piwik automatically groups pages, keywords, websites, etc. under the label "Others"; How do I force Piwik to not limit the data? - Analytics Platform - Piwik
