Help talk:CirrusSearch/en

I have enabled the CirrusSearch extension, and I have these settings in my LocalSettings.php:
$wgRelatedArticlesUseCirrusSearch = true;
$wgSearchType = 'CirrusSearch';
$wgVectorUseSimpleSearch = true;
$wgUseAjax = true;

I'm getting search suggestions for titles that start with what I'm typing into the search box, but no suggestions for titles that contain what I'm typing. I see this is also the default behaviour in wikipedia, which is understandable since wikipedia is such a huge wiki, results need to be limited. Since my wiki project is just starting, I would rather include results that contain anywhere in the title what is being typed into the search box. How would I go about enabling this?

The section on hastemplate: should indicate that a) the search terms are not case-sensitive, and b) there is optional white space between hastemplate: and its quoted argument, but there cannot be white space between hastemplate and its colon.
