  1. Document renaming | GroupDocs

    Sometimes a situation arises when an indexed document is renamed, but its contents have not changed. In this case, to save computing resources, you can notify the index about the renaming of the document, and then the document will not be reindexed during the update operation. To notify an index about renaming a document, the notifyIndex method is used with the corresponding notification object as a parameter. You should keep in mind that if an index is notified of the renaming of a document, it will not be reindexed the next time you call the update method, even if its contents have changed....Sometimes a situation arises when an indexed document is renamed, but its contents have not changed.

  2. OCR support | GroupDocs

    OCR support means the ability to connect an external module (library) for the recognition of printed text (optical character recognition, OCR) on images, either separate or embedded in documents. To connect OCR, you need to implement the IOcrConnector interface in the client code. The following example demonstrates how to implement the OCR connector using com.aspose.ocr library for text recognition in images. const indexFolder = 'c:/MyIndex/'; const documentsFolder = 'c:/MyDocuments/'; const query = 'Einstein'; // Creating an index const index = new groupdocs....OCR support means the ability to connect an external module (library) for the recognition of printed text (optical character recognition, OCR) on images, either separate or embedded in documents.
