# Generate PDF Search Previews on iOS

[`PDFLibrary`](https://www.nutrient.io/api/ios/documentation/pspdfkit/pdflibrary) can also generate a small snippet of text around each match it finds. When calling [`documentUIDs(matching:options:completionHandler:previewTextHandler:)`](https://www.nutrient.io/api/ios/documentation/pspdfkit/pdflibrary/documentuids(matching:options:completionhandler:previewtexthandler:)), if the `previewTextHandler` parameter is not `nil`, [`PDFLibrary`](https://www.nutrient.io/api/ios/documentation/pspdfkit/pdflibrary) will also generate previews. Note that preview generation will have a performance impact, as additional information needs to be extracted from the database. [`PDFDocumentPickerController`](https://www.nutrient.io/api/ios/documentation/pspdfkitui/pdfdocumentpickercontroller) leverages preview generation when displaying results, as shown below.![Preview example](@/assets/guides/ios/features/indexed-full-text-search/ios-document-picker-controller.png)
