Using Create Full Text Indexes, you can create an index that contains a catalog of PDF documents. An index is especially useful when you want to search cataloged PDF documents for certain information. The search engine searches the selected index rather than the documents themselves, making the search process much faster.

To create an index

When you create a new index, an index file (*.zpi) is created along with a support index file that contains one or more files.

  1. Open a PDF file and choose Basic > Search > Index . Click the down-pointing arrow to the right of Index and select Create Full Text indexes… from the menu.

  2. In the Catalog dialog box, type a name for the new index.

  3. In Description, enter a few words to describe the purposes or the type of the index.

  4. In Stop Words, enter words you want to ignore during the index search process and click Repeat it to add more words. To remove an item from the list, click to highlight one and click Del.

  5. In Custom Field, type a field name, select a type for the index and then click Add.

  6. Under Include Directory, click Add and locate a folder containing some or all of the PDF files to be indexed and then click OK. Repeat this step to add more folders. To remove a folder from the list, select one and click Del.

  7. Under Exclude Directory, click Add and select any nested folder that contains PDF files you do not want to be indexed and then click OK. Repeat this step to add more folders. To remove a folder from the list, select one and click Del.

  8. Click Build, give the (*.zpi) file a name, and specify a location for it. Click Save.

  9. The Building dialog box shows the progress of indexing. You can click Stop to cancel the indexing process or click Close when the indexing process finishes. Note that if canceling the indexing, you cannot resume the same indexing session anymore but you don’t have to redo the work. All the settings and folders chosen remain intact. You can simply click Open, select the partially finished index and revise it.

To revise an index

You can rebuild, purge an existing index folder, or create a new index with the existing information.

  1. Open a PDF file and choose Basic > Search > Index.

  2. Click the down-pointing arrow to the right of Index and select Create Full Text indexes… from the menu.

  3. In the Catalog dialog box, click the Open button located next to the File field. Locate and select an existing Index File (*.zpi) and then click Open.

  4. Make changes to the selected index as needed. Click Close:

    • Build. Create a new index file with the existing information, and update it by adding new entries and marking changed entries as invalid. If you make a large number of changes or use this option repeatedly instead of creating a new index, the time needed for searching may increase.

    • Rebuild. Create a new index by overwriting the existing index folder and its contents.

    • Purge. Delete the index contents (all files in the index folder) without deleting the index file (*.zpi) itself.
