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.

Sometimes when indexing, it is necessary to associate each document with certain additional metadata, for example, a set of tags, a number in the library catalog, the subject of a document, etc. To accomplish this task, additional fields can be added to each indexed document in addition to those already in the document itself.
Additional fields are associated with the document through the arguments of the FileIndexing event that occurs before indexing each added document....Search Product Solution GroupDocs...GroupDocs.Search Product Family / GroupDocs.Search for Node.js...
