For now, you can only search the textbase if you don't use that box. The field searched by the box where you typed the comparison search doesn't have Term index. Solution Change your search so it doesn't use any of the comparison operators. If you're searching for text which includes any of these symbols, enclose the search text in quotes or replace the symbol with a space. You can also contact the webmaster for the site where this textbase resides and ask them to use Edit Textbase Structure to add a Term index to the field.
Proximity searches require a word index.
Then change your search so it doesn't do a proximity search in that QBE box. Cause You typed a search which attempted to search a field from a secondary textbase. You cannot search secondary textbase fields until the problem is corrected. If the textbase has passwords, the password you are using may hide the linked information. Return to the search screen and specify a password gives you access to the linked information.
