OCR Documents for Full Text Indexing

With the Imaging System, Users have access to the Xerox TextBridgeÒ engine, a powerful Optical Character Recognition (OCR) tool. Put simply: the OCR process reads scanned Document images into editable text files. Users then add the output to one of the online Indexes, parsing the text file into an expandable wordlist. When the Indexing is complete, Users can perform keyword searches on the contents of all files added to an index. Results from this search are linked back to the Document images stored in the Imaging System; thus, every Document can be indexed, word for word.

The system splits the screen into two panes: the Document Image appears in the top pane, the editable text appears in the bottom pane. OCR output text is edited in the bottom pane.

Full Text Search for Indexed Documents

 After Documents have been OCRed and indexed, Users can search an Index  for Documents containing keywords or phrases. The Full Text Search engine provides several advanced search mechanisms such as the logical operators “AND” and “OR”, along with others detailed below. When the system finds a “hit” or occurrence of the requested word or phrase, the Document(s) can be viewed with each hit highlighted in red.

When using multiple connectors, parentheses denote how relationships are grouped. For example, the string “apple and pear or orange” could mean “(apple and pear) or orange”, or it could mean “apple and (pear or orange)”.

Search terms and ranges may include the following:

a.       matches to any single character;

b.       matches to any number of characters;

c.       fuzzy search;

d.       phonic search;

e.       stemming (forms of words ending in es, s, ing, ed, etc.);

f.         synonym search;

g.       numeric range

h.       date range

 The system displays the text file in the left pane and the Document Image in the right pane. Hits are displayed in red.

The file can be opened in a word processor such as MS Word below, as well as in the Full Text search.
