|Subject: [PATCH] searchengines: allows simple use of search engines
|
|The previous patches had some issues:
|* don't apply cleanly to the latest version.
|* a space between the token and query is implied, so having " " as a
|  token means you actually have to use "  ". Or if your token is "e",
|  searching for "example.com" would trigger it. Now you specify the exact
|  token to look for.
|* has checks to skip badly configured search engines. The correct
|  solution is to configure them right.
|
|Now it works like a better version of the spacesearch patch, as it
|allows you to specify " " as a token
