DSFFullTextSearchIndex

dsffullTextSearchIndex

使用SQLITE FTS5的簡單iOS/MACOS/TVOS全文搜索（FTS）類，使用類似的API與SksearchKit相似，沒有外部依賴關係

為什麼

我想在我的MacOS/iOS應用程序中添加全文搜索索引，並意識到SksearchKit（因此DFSearchKit僅是MacOS。

SQLite具有可通過的固體FTS功能，我希望能夠以與SkSearchKit相似的方式使用它們。我還想要一個沒有任何依賴性的簡單包裝器。儘管我愛GRDB，但我當然不需要它提供的所有內容。

我也想要兩者都可以的東西： -

• 在沒有傳統數據庫的應用中獨立工作，並且
• 在具有現有SQLITE數據庫的應用程序中工作。
• 可以在iOS，MACOS，MACOS（CATALYS）和TVOS上的應用程序之間共享。

簡單示例

// Create an index

let index = DSFFullTextSearchIndex ( )
index . create ( filePath : /* some file path */ )

//
// Add some documents
//
let url1 = URL ( string : " demo://maintext/1 " )
index . add ( url : url1 , text : " Sphinx of black quartz judge my vow " )

let url2 = URL ( string : " demo://maintext/2 " )
index . add ( url : url2 , text : " Quick brown fox jumps over the lazy dog " )

let url3 = URL ( string : " demo://maintext/3 " )
index . add ( url : url3 , text : " The dog didn't like the bird sitting on the fence and left quietly " )

//
// Search
//
let urls1 = index . search ( text : " quartz " )   // single match - url1
let urls2 = index . search ( text : " quick " )    // single match - url2
let urls3 = index . search ( text : " dog " )      // two matches - url1 and url3

// Search with a wildcard
let urls4 = index . search ( text : " qu* " )       // three matches = url1 (quartz), url2 (quick) and url3 (quietly)
