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.

If you want to use a different language wikipedia site, you can change the one Searchify searches in Searchify Settings.

You can also choose how many wikipedia search results are returned, and whether or not to use wikipedia mobile.

The built-in shortcuts are:

• twt (to search Twitter)
• dict (to search Google Dictionary)
• meta (to search Metacritic)
• imdb (to search IMDb)
• slang (to search Urban Dictionary)

To add your own, go to Searchify Settings, bring up the menu, and select “Add new item”. You’ll have to enter the search URL you want the shortcut to link to, with “%s” where you want the search term to go.

Translations are shown in a number of different languages.  You can choose which languages you want to be returned in Searchify Settings.

If the translation is too long to fit in the result box, tap the result to see the whole thing.

If you don’t want to have to type “translate” every time, you can change or remove that keyword in Searchify Settings.

You have to have an internet connection for the translation to work because it’s Powered by Google.

Some examples:

• 15 + 12
• 145 – 27
• 3 x 5
• 375 / 5
• 4 + ( 3 x 5 )
• cos(0.1)
• 50 * sin(pi/2) + ln(7^2)

The full list of supported symbols is as follows:

OPERATORS: +, -, ×, ÷, ^

FUNCTIONS: sin, cos, tan, asin, acos, atan, log, ln, sqrt

CONSTANTS: pi, e

For the trig functions sin, cos etc., Searchify by default uses radians, but you can change this to degrees in Searchify Settings.

For each calendar on your phone that you can add events to you’ll see an item in the search results.  Just tap it to add the event.

Some examples of what you can enter:

• today 3pm meeting
• tomorrow 15:00 another meeting @ London Office
• tue 1750-1900 drinks @ the bar
• tuesday 9pm-3am party @ Sarah’s
• fri-mon City Break @ Barcelona
• 15/3 0900 interview

• 03/15/2010 9am interview (if your phone uses US date format)
• 18/04/2010 3pm – 25/04/2010 7am long event

Events have to have a start date and a description, but the other bits are optional.  If you don’t give an end time, Searchify sets a duration by default (usually one hour, but you can change this in Searchify Settings).

If you want events created by Searchify to have reminders you can do this, just select the option in Searchify Settings.

Searchify recognises different ways of writing units, so you can enter “10lb” or “10 pounds”.
