Abstract

The invention relates to a method and an arrangement for paginating and previewing essentially continuously-flowing non-paginated search results, such as XHTML/HTML formatted information content. The method includes at least: entering a search query; sending the query to a search engine; and receiving a search result having a list of data files matching to the search query. The method comprises at least: paginating the essentially continuously-flowing content of the data files retrieved; rendering preview pages from the data files; selecting the preview pages to be previewed; and previewing the matching preview pages associated with the data files retrieved.

Claims

1. A method for paginating and previewing content within one or more data files received in response to an information search, the content within the one or more data files being in an essentially continuously-flowing non-paginated format, wherein information content within the one or more data files include content formatted by markup language code, the method comprising:

entering a search query;

sending the query to a search engine, and receiving a search result having a list of data files each of which comprises content represented in a markup language code matching the search query; and

for each of the data files in the list;

retrieving the data file;

paginating the content of the retrieved data file into discrete pages by applying pagination rules for dividing the content of the retrieved data file into multiple parts each suitable for page-level previewing purposes;

generating preview pages each for rendering the same visible content of the retrieved data file that has been paginated into a respective discrete page of the retrieved data file;

sending the preview pages to a client device which constructs a data file preview for the data file that simultaneously displays a subset of the preview pages generated for the data file, each of which is automatically selected for display in the data file preview by virtue of containing content that matches the search query,

wherein the constructed data file preview is configured to allow an end user of the client device to select preview pages, which are displayed in the data file preview, in order to view higher resolution versions of those preview pages matching the corresponding discrete pages of the retrieved data file.

2. The method of claim 1, wherein the data file content is paginated into the discrete pages based on system rules, user configuration and operating environment preferences.

3. The method of claim 1, wherein the preview pages are indexed for the content filtering, and wherein the selected preview pages are selected according to the results of the content filtering.

4. The method of claim 1, wherein

the preview pages are rendered to HTML and image files, or vector files, and

the data file preview is compiled from a layered presentation of HTML content and image content associated to the corresponding area of the original data file, or from a vector file.

5. The method of claim 1, wherein at least one or more image files are created from each of the preview pages.

6. The method of claim 1, wherein

keyword(s) or phrases of the search query are highlighted page previews that are automatically selected for display in the data file preview.

7. The method of claim 1, wherein the search result area is reserved to display the preview pages generated from the data file.

8. The method of claim 1, wherein the selected preview pages are displayed in an m by n matrix format in the data file preview, and a user selectable zoom-in to the preview pages is provided within the matrix format.

9. The method of claim 1, wherein the selected preview pages are displayed in the data file preview in connection with the data file information provided by the search engine.

10. The method of claim 1, wherein the preview pages are populated essentially immediately in an m by n matrix in the data file preview when preview data becomes partially available.

11. The method of claim 1, wherein preview pages that are not currently displayed in the data file preview are pre-loaded in the memory of the preview engine for later viewing.

12. The method of claim 1, wherein one or multiple preview pages of each data file containing matching keyword(s) is shown to the user.

13. A system for paginating and previewing content within one or more data files received in response to an information search, the content within the one or more data files being in an essentially continuously-flowing non-paginated format, wherein information content within the one or more data files include content formatted by markup language code, the system comprising:

one or more clients with a processor, a user interface, and a communication interface to a network that facilitates a connection between the clients and a search engine; and

a preview engine that performs the following;

receives a search result from the search engine in response to a query sent to the search engine, the sear result having a list of data files each of which comprises content represented in markup language code matching the search query, and

for each of the data files in the list;

retrieves the data file;

paginates the content of the data file into discrete pages by applying pagination rules for dividing the content of the retrieved data file into multiple parts each suitable for page-level previewing purposes;

generates preview pages each for rendering the same visible content of the retrieved data file that has been paginated into a respective discrete page of the retrieved data file;

sending the preview pages to a corresponding client device which constructs a data file preview for the data file that simultaneously displays a subset of the preview pages generated for the data file,

wherein, for each of the data files, the preview engine automatically selects from the preview pages generated for the data file the preview pages to be displayed in the constructed data file preview by virtue of the selected preview pages containing content matches that matches the search query, and

wherein the constructed data file preview is configured to allow an end user of the client device to select preview pages, which are displayed in the data file preview, in order to view higher resolution versions of those preview pages matching the corresponding discrete pages of the retrieved data file.

14. The system of claim 13, wherein the preview engine has at least a user interface manager, connectors, a content converter, a page indexer, and a cache manager.

15. The system of claim 14, wherein the content converter is configured to paginate the content of each of the data files in the list to generate the preview pages.

16. The system of claim 14, wherein

the connectors are equipped to connect the preview engine to the search engine and to content servers, and

the connectors are configured to:

send a user search query to the search engine,

receive search result lists from the search engine, and

download the data files from the content servers to the preview engine.

17. The system of claim 13, wherein at least one of the data files is a static file stored at a content server.

18. The system of claim 13, wherein at least one of the data files is a dynamic stream of data, which is generated by a content server when requested.

19. The system of claim 14, wherein

the cache manager is configured to store and retrieve folder data and the preview pages with associated meta-data into a storage, and

the page indexer is configured to index the preview pages for filtering purposes, and search and select the matching preview pages for display in the data file preview.

20. The system of claim 13, wherein

the user interface of the corresponding client has at least a search result list area for displaying a list of search results containing at least one or more data file hits provided by the search engine, and

the system is configured to reserve a search result area to display the selected preview pages in the data file preview in an m by n matrix format.

21. The system of claim 13, wherein

the preview pages are displayed in the data file preview in connection with the data file information provided by the search engine, and

the data file preview has a display area to present preview pages in m by n matrix.

22. The system of claim 13, wherein the user interface of the corresponding client comprises a button, link or area adapted to be clicked by a user for additional preview pages.

23. The system of claim 13, wherein

an output screen created by the preview engine comprises navigation buttons, links or areas adapted for a user to navigate backward and forward through preview pages stored in the memory, and

the preview engine provides one or more buttons adapted to be used to navigate between the search result list provided by the preview engine.

24. The system of claim 13, wherein the selected preview pages are displayed in the data file preview in a matrix in a new output screen, and are user selectable for zoom-in pages.
