Today, many different publications such as journals and books are presented in electronic environment. Copyright concept is still discussed about the distribution of the books and paid publications digitally. The main objective of electronic library application to be developed is to display a certain part of the books and publications including the information that the users intend to reach. In this study, such operations as the search of phrases within various portable document format (PDF) documents like e-books, theses and technical reports or on the bookmarks of the documents, and the generation of its results as a PDF document have been showed. It has been viewed that the phrase search process gives more accurate results than the search on bookmarks, but is slower. As a result of the studies conducted on PDF documents specially created according to parameters such as file size, number of pages, content type and number of bookmarks, it has been observed that these parameters affect search performance at different degrees. In addition, an open source plug-in that can perform these operations has been also developed for the electronic library application. The plug-in developed independently of electronic library application in Java programming language can easily be added to the web applications. Apart from the plug-in, there is also a lot of information required for users to create and manage their own PDF documents.
