After making preparations, you can start to create an index.
To create a full text index
Choose Advanced Processing > Process > Index and choose Create Full Text Indexes in the drop-down list.
Click New in the Catalog dialog box.
Type an index definition file name in the Title field.
In the Description field, type general words that can properly describe the document.
Add words in the Stop Words field that you want to have ignored during searches.
Add custom terms for the index in the Custom Field.
Click Add next to Include Directory to select a folder whose PDF files should be included in the index. Repeat the step to add more folders. If you plan to later move the PDF files with their index to a server or web site, it is better to group them in a single folder.
Click Add next to Exclude Directory to select a subfolder nested in a folder that is listed in the Include directory list. Repeat as desired. The selected subfolders will be excluded from indexing.
Click Build, and then specify the location for the index file. Click Save.
Excluding specific words
Common words such as a, the, at, of, and for can be excluded from indexes. Stop words can contain up to 128 characters and are case sensitive. Excluding such words can make an index 10% to 15% smaller which will improve search efficiency. However, users cannot search using phrases that contain stop words. So if you pass a Readme file to colleagues along with an index, this should list the excluded stop words.
To exclude words from indexing
Choose Advanced Processing > Current Document > Index > Create Full Text Indexes.
Type a word to be excluded in the Stop Word edit box and click Add. Repeat as needed to exclude more words.
To remove a word from the Stop word list (that is, to include it again in the indexing process), select the word, and click Del.
After an index is created, it can be embedded into the current document.
