Well, I don't understand whet do you mean "index your document with the
keywords assigned to the document". Thre is no keywords assigned to a
document. I was thinking in his way - may, is it possible to index the
database of keywords, and use entire document as search phrase?

Sould that find single words as well a phrases?

For example, if document contains a phrase

some things happens there

and there are entries in keywords database

some things
happens here
some things happens here

I will need to get all of these entries.

This database could be VERY large, several millions of records.
