Modules & VBA :: Can't Find And Format Section Of Text Within RTF Memo Field

I had the need every so often to quickly find all instances of any (particular) word within the database, without going to the bother of thinking about where that word/subject might be in the data base, I designed a report which does the job nicely. It uses a search form/control, searches and finds all instances of the word (or words) I have asked it to find, then does a report showing all instances of whatever RTF memo fields that contain the word(s).It has to be RTF memo field because (if I wish) it goes straight into the book text I'm writing, and also it searches the book's RTF memo field.
.
The trouble is, at present, I then have to manually "eye scan" the resulting report to find the occurrences of the "key searched for" word, nestling/hidden somewhere within sometimes quite large chunks of text. I would love to have the report show the found "key word(s)" highlighted in (say) light blue or whatever colour, so that I can quickly & easily lock on to it visually.

I enter the word I want Access to find, into a form called "formfindword" in a text box called Text0. I click on a command box on this form, to open up the report called "Querywhatsandhowschooseword" based on a query of the same name. The query's "what" field (from the main database) has the criteria

= Like "*" and [forms]![Formfindword]![Text0] & "*"

The query's "how" field criteria (in the "or" line of the query design) is also

= Like "*" & [forms]![Formfindword]![Text0] & "*"

I have tried to use the Conditional Format facility in Report Layout view, without any luck.I think therefore that I will need some VBA code (which is totally foreign to me, unfortunately) to make this simple concept a reality.
