Language Pack for Standard/Tesseract OCR
All versions of the SimpleIndex software include OCR with the Standard/Tesseract OCR engine. The SimpleIndex download only includes a limited set of languages with the installation. If the language you would like to OCR with SimpleIndex isn’t one of the languages included then you can download your required language(s). Once you do this you will be able to pick the language that you want to read with the Standard/Tesseract OCR engine.
- Go to the Tesseract Language Download Site
- Select the language you want and download or download all the language
- Copy the language files (unzip if downloading more than one language) to this folder: C:\Program Files (x86)\SimpleIndex\Tesseract\v3.04\tessdata
- Close and Reopen SimpleIndex and the downloaded languages will now be selectable
Languages Supported in SimpleSoftware OCR Engines
SimpleSoftware OCR engines are using two different systems for language support. In the end languages supported by your OCR is based on your version of SimpleIndex installed, any addons (SimpleIndex Server, SimpleCoversheet, and so on) do not add any additional language support.
All SimpleSoftware products have Tesseract 3.02 OCR languages support. You can learn more about it and download additional language libraries HERE. And you can check and add more OCR languages libraries supported with Tesseract on your station here:

What is Document Imaging?
Document Imaging was the more commonly used term in the early days of document scanning and OCR and refers to any system used to replicate documents used in business. It evolved from the microfilm days where it was referred to as Document Image Management.
Document Imaging allows for the scanning of paper documents, as well as the processing of files saved electronically. These files are then named and saved for later searching.
Other document imaging terms include automatic imaging software, best digital imaging software, best imaging software, desktop imaging software, digital document imaging, digital imaging software, document imaging download, document imaging PDF, document imaging processing, document imaging products, document imaging software, document imaging solution, document imaging solutions, document imaging systems, document imaging technologies, document imaging technology, document imaging tools, image to database, imaging resource, imaging scanning software, imaging software companies, imaging software download, imaging software for windows, imaging solution, scanner imaging software, scanning and imaging, scanning imaging, and software for imaging.
Change the Dictionary Separator Value
This is used to change the dictionary separator value when doing thesaurus matching from the default character of | to any character(s) that you want. This can be useful in cases where the values you would like in your list or dictionary might include the pipe character or “|” or “Shift Backslash”
This setting is also used as the delimiter when parsing multiple index field values from bar codes (e.g. field1|field2|field3).
Instructions for changing the dictionary separator value:
- Right click on the Job Configuration file that you would like to suppress the prompt on and select Open With>Notepad
- Search the XML settings text open in Notepad for this term:
- Change the value in-between from “|” to any other single character that you want.
- For TAB separation use %TAB%
Change the OCR Font or Type
This is used to changed the default OCR recognition font or type from the default, which is “To Be Detected”. This can be used to look for a specific type of OCR font and is especially useful for recognizing things like Dotmatrix, OCR A and OCR B.
Instructions for setting OCR Font:
1. Right click on the .sic file and select Open With a text editor (Notepad, Wordpad, etc.)
2. Find <OCR_TEXT_TYPE>. If you can’t find <OCR_TEXT_TYPE> then add the following as the last row in the text file:
3. Change the number in between: <OCR_TEXT_TYPE>#</OCR_TEXT_TYPE>
4. Number of desired font:
- 0 Normal
- 1 Typewriter
- 2 Dotmatrix
- 3 Index
- 5 OCR A
- 6 OCR B
- 7 MICR E13B
- 8 MICR CMC7
- 9 Gothic
- 10 To Be Detected
5. Close and save file
Regular Expression (RegEx) – Syntax or Type
SimpleIndex uses the .NET regular expressions library.
For more information see the Regular Expressions Wiki Page.
Autonumber Increment Value
If you want to change the value of how much the Autonumber Increments each time from 1 to any number that you want then do the following:
1. Right click on the configuration file and “Open With” any text editor, such as Notepad.
2. Search for the following:
3. Change the number in this entry to the amount that you want the Autonumber to Increment:
4. Save the configuration file.
I’m using full page OCR. The information is all appearing in the txt file but it is losing format about half way through. Data to the right is ending up at the end of the txt doc. Can this be fixed?
SimpleIndex version 7 solves this problem with the incorporation of the FineReader OCR engine. Full text in PDFs will now flow with the formatting of the PDF.
Legacy Versions: SimpleIndex can also be used with other OCR applications and servers to improve accuracy, formatting and performance. Use the OCR applications to convert the scanned images to text or searchable PDF, and SimpleIndex can extract index values from the text and automatically sort and organize the files.

Is there a way to just use part of a bar code or OCR value? For example, extract “50” from the value “124450”
To do this example, create a barcode field (Field 1 for example) and a 2nd field with type “Fixed”. In the template for the 2nd field, enter %FIELD1[5,2]% to get “50” from “124450”.
%FIELD1% would get the entire value for Field #1, the barcode field. By adding the [5,2] you tell SimpleIndex to start at the 5th character (5) and take 2 characters from the value (50).
Find out more about barcode scanning on our Barcode Scanning Guide and read up on Optical Character Recognition on the SimpleOCR scanning solutions guide.

How do you configure full text searching in Retrieval mode?
On the Database tab there dropdown in the lower portion of the panel for Full Text OCR Field. Put the name of the field that will store the full-text data there. This must be configured both for Insert and Retrieval mode configurations. The database field needs to be sufficient length to store the entire text of your document.
Of course, the Insert Mode configuration must have “Enable Full Page OCR” checked to generate full text data from images. Text from MS Office documents, PDF files and existing OCR text files can be used without setting this option.
When designing your Retrieval Mode configuration, create a Text field to use for full text search queries. On the Database tab, set the corresponding “Database Field Name” to the full text database field.
When searching on your full text field, SimpleIndex finds the text you enter no matter where it appears in the document. It is able to match partial words. It does not perform boolean or natural language searches. The text entered must match the document text exactly.

How do you configure OCR to read index information from MS Office or PDF documents?
MS Office and PDF files generated by software or PDF printer drivers already have the text you need to recognize in the file. Scanned documents need to use OCR to read text from an image of the page. With Office and PDF files, SimpleIndex can just read the text, which is much faster and accurate than image OCR.
To recognize index fields from the document text, first create OCR fields on the Index tab as you would normally. Next, on the Zones & OCR options tab, check the “Use Full Page OCR for this Field” option for each OCR field. This tells SimpleIndex to process the existing file text.
If the index value is a unique pattern of digits or list of possible values, use Template or Dictionary matching to locate the value within the text. Please see the manual for details on Template and Dictionary matching.
If the value appears in a specific location in each file, coordinates can be used to locate it. When processing text, the X, Y, Width and Height settings correspond to line and column numbers within the file text. This is explained in greater depth in the manual.
SimpleIndex will assume that any TXT file with the same name as a file being processed is the OCR text for that file, so this method can work with any type of file.

How can I improve recognition rates for my OCR fields?
There are several things you can do to improve accuracy for OCR.
- Scan at 300dpi, black & white for best results.
- Adjust the scan settings to remove background noise and improve the definition of characters.
- For Zone OCR, field recognition can often vary based on the surrounding white space and text in the zone. Try varying the size of the zone to achieve optimal results.
- For template matching, make sure all variations of the field format are included in the template list.
- For dictionary matching, add common variations and OCR mistakes to the “thesaurus” list.
- On the Zones & OCR tab (accessed from the Job Options) you can adjust the Max Errors setting to allow for more mistakes in the dictionary matching process.
- Use the Strip Spaces, Strip Characters, Replace Characters and Case Fixing options to standardize the field format prior to matching.
Please refer to the SimpleIndex Wiki for details on how to configure these options.

Can OCR text be saved to Office, Text, HTML or other formats?
Yes. On the OCR step of the Job Settings Wizard you can select the text output format need in the “Full-page OCR file type” drop down. By default it is set to PDF, but can be changed to Text (txt), Word (docx), Rich Text (rtf), Open Office (odt), Excel (xlsx), PowerPoint (pptx), ePub Zip (epub), FictionBook (fb2), HTML (htm), XML (xml) or Alto XML (alto.xml).
If the output file type is set to PDF, OCR text will be embedded as hidden text in the PDF file.
