If you prefer to manually edit your configuration files, use the following syntax for this option:

searchkeywordsbyserver on
searchkeywordsbyserver off

This option is only useful if your server logs contain referrer information as an extra field, optionally in quotes, after the regular common log format fields, or if you have a separate referrer log. See the server notes section for information on configuring popular web servers to log this information in the best possible way. If you have a separate referrer log, use the -r command line option and the -l filename command line option when starting Wusage. This produces a special summary report called referrers.html (note the spelling) in the report directory. It is best to configure your server to log the information in the main log file so it can be included in regular reports. If your log does not contain referrer data, this report will not contain useful information!

The Show Top Search Keywords By Search Server Used ^{(searchkeywordsbyserver)} report provides a complete breakdown of the Internet search keywords most frequently used to reach your web server via each individual search server. There are many search servers on the Internet, and the Search Server Templates ^{(searchservertemplates)} option is used to inform Wusage about the servers you consider important. Configuration files created through the user interface automatically include templates for many major search servers.

If present, the Show Top Internet Search Keywords ^{(searchkeywords)} option indicates that wusage should output information about the "search phrases" that were most often used to find your server via each distinct search server. Note that browsers do not always report this information, and that not all search servers provide it in the referring URL. If the Show Top Search Keywords By Search Server Used ^{(searchkeywordsbyserver)} option is absent, or set to off, a report will not be generated. You may receive unexpected results if your logs do not contain referrer information.

For a more compact report which ranks the overall popularity of search phrases, see the Show Top Internet Search Keywords ^{(searchkeywords)} report. For a report ranking search servers by frequency of use, see the Show Top Internet Search Servers ^{(searchservers)} report.
