IGSearch 0.3.2

  • By
  • Francis Chong and Steven Gravell

A simple Objective-C full text search engine with CJK support.

Why

  • Core Data search do not built in full text search.
  • SQLite3 bundled with iOS do not have proper tokenizer that support CJK language full text search.
  • A simple and easy to use API, independent with the data model.

Setup

Use CocoaPods, add following to your Podfile

pod 'IGSearch'

Run pod install and you're off!

Usage

First, create a database.

IGSearch* search = [[IGSearch alloc] initWithPath:aPath];

Then, index documents.

[search indexDocument:@{@"title": @"Street Fighter 4", @"system": @"Xbox 360"} withId:@"1"];
[search indexDocument:@{@"title": @"Super Mario Bros", @"system": @"NES"} withId:@"2"];
[search indexDocument:@{@"title": @"Sonic", @"system": @"Mega Drive"} withId:@"3"];
[search indexDocument:@{@"title": @"Mega Man", @"system": @"NES"} withId:@"4"];

Search the document is simple:

[search search:@"Street"]; // @[ @{@"title": @"Street Fighter 4", @"system": @"Xbox 360"} ]
[search search:@"Mega" withField:@"title"]; // @[ @{@"title": @"Mega Man", @"system": @"NES"}  ]

Or search only the document ID:

[search search:@"Mega" withField:@"title" fetchIdOnly:YES]; // @[ @"4" ]
