Searchify

Froyo changed the Quick Search Box to make it case-sensitive.  This meant that keywords had to be typed with the right casing (so e.g. “Cal” would not work for “cal”). This update fixes this so that keywords are never case-sensitive.

The changes aren’t too big – you can still just type into the search box and some Searchify results may appear below.  But now the box usually only shows one or two Searchify results – it prefers to show you Google results.

There’s an easy way to see Searchify results though – the new search box (that comes up when you press the search key) has a g icon next to it that you can tap.  If you do, you see icons for all the kinds of searches you’ve enabled.  You should see Searchify here – if you don’t, you need to activate Searchify in your phone’s settings.

Tap the Searchify icon to see only Searchify results from your search query.

Widget: With 2.2 you can also now create a Searchify widget.  Go to the Add Widget menu and choose a “Google Search” widget.  A menu will pop up asking what kind of search widget you’ll like.  If you’ve activated Searchify, it’ll be one of the options.

A few other points:

• Searchify is great with 2.2′s extra speed!  All the app’s features fly now, including calendar search and wikipedia search.

• After upgrading to 2.2 you might need to re-activate Searchify in your phone’s settings

• Searchify calendar features won’t work unless you have the new version 1.1.3 version of the app

• fixes issue where some all-day events in calendar search were being shown with the wrong date

• adds power and torque units to the unit convertor

From the settings screen, press Menu then go Options -> Wikipedia.  Or tap-and-hold on the Wikipedia entry in the main settings screen.  You’ll see “Wikipedia language” setting and will be able to choose the wikipedia language.

To use it, type the keyword cal followed by the words you want to search for.  If you don’t want to type “cal” every time, you can change or remove that keyword in Searchify Settings.

Calendar search brings back both past events and future events.  In Searchify Settings you can set how far back in the past and future you want it to look – the default for this is one year in the past and two years in the future.

You can also choose in the settings how many results should be brought back, and whether or not you want the location field to be searched as well as the event titles.
