Abstract
Methods and apparatus for retrieving PDF documents, performing text extraction operations on portions or all of a retrieved document and supporting search operations in a manner that allows search results to be quickly provided for at least portions of a PDF document being viewed are described. The methods and apparatus are particularly useful in applications, such as many applications executed by a browser, where the application is limited to a single processing thread and thus must perform all or many processing operations sequentially. By prioritizing document pages which are being viewed for text extraction even before a search is initiated and by performing text extraction in small periods of time and storing the results, in many cases a user can be provided with text search results for a page being viewed in relatively little time and without the program, e.g., java script browser application, appearing non-responsive.
