Search Limit: 100

The maximum record number that returns for a single query is 100 as default. The number can be set to a smaller one by setting the "limit" parameter.

When the number of search results exceeds the maximum number, the value of "is-limited" will be set to "true". It means that not all of the search results were written in the returned text, so please be careful to discuss about the results.

The "is-limited" value is written in the returned text when the "output" parameter has been set to "txth" or "xml".
