You probably know that Contact Lookup Fast on Android can search your contacts, but it can do more than that.
In the video below, we show how you can search for employees of Microsoft by using the organisation category prefix (o:). This quickly pops up the employees, but we notice that one suspicious employee is from Finland, so we modify the search to exclude anyone from Finland* using the exclusion modifier (!).
Having searched, we can then email, sms or send their vCards using the share option. This opens another screen where you can tailor the list to exclude people or change the contact address.
* Technically we should have used the address category (a:!finland) to make sure we only exclude people with addresses in Finland, as without the category prefix CLF would exclude any contact with Finland in any field.
Contact Lookup Fast is available from the Google Play Store.
