Field 

Description 

dtsoFilterBinary 

Filter text from binary files using the character array in binaryFilterTextChars to determine which characters are text. This option is not recommended. Use dtsoFilterBinaryUnicode instead for more effective text extraction from binary data. 

dtsoFilterBinaryUnicode 

Filter text from binary files using a text extraction algorithm that scans for sequences of single-byte, UTF-8, or Unicode text in the input. This option is recommended for working with forensic data, particularly when searching for non-English text. 

dtsoIndexBinary 

Index all contents of binary files as single-byte text. This option is not recommended. Use dtsoFilterBinaryUnicode instead for more effective text extraction from binary data. 

dtsoIndexBinaryNoContent 

Index binary files disregarding all content within the file. Only the filename and any fields supplied externally to the file, such as in DocFields in the DataSource API, will be indexed. 

dtsoIndexSkipBinary 

Do not index binary files
