To see if a database already has a full-text index, choose View - Search This View, and look for the green indicator:
You must have Designer access or higher to create a full-text index for a database. Call your Domino administrator if you want to full-text index a database for which you don't have at least Designer access. Only your Domino administrator can full-text index a database on the Web.
A full-text index can be about 10-20% the size of the database itself (depending on how much text is in the database). You may want to make sure you have the space before full-text indexing a very large database.
To create a full-text index for a database
1. Open the database.
2. From the menu, choose View - Search This View.
3. In the lower right corner of the Search bar, click More.
4. Click "Create Index."
5. Select full-text index options.
6. Click OK.
