<description>Search engine file names have &quot;.search&quot; as postfix. When they are clicked, the associated bookmark files with postfix &quot;.search.html&quot; would be appended. Ex: the associated bookmark for &quot;foo.search&quot; is &quot;foo.search.html&quot;.
Any &quot;.search&quot; file can be opened as search engine file, each line of which has one of the following formats:
[Engine name]:[url without '%s' inside]
[Engine name]:[url with '%s' as keyword]
[Engine name]:POST:[post params with '%s' as keyword]:[url]
[Engine name]:[Extra request headers]:[post params with '%s' as keyword]:[url]</description>
