Subject Re: fast case-insensitive autocomplete
Date Thu, 05 May 2011 20:58:08 GMT
Hi,

I haven't used Suggester yet, but couldn't you feed it all lowercase content and 
then lowercase whatever the user is typing before sending it to Suggester to 
avoid case mismatch?

Autocomplete on http://search-lucene.com/ uses 
http://sematext.com/products/autocomplete/index.html if you want a shortcut.
