Thanks for the help Jimsafley. You solved it
Id set the ‘extracted text’ to private because when the text appeared on an Item page, it made the page so long.*
This meant when not logged in (ie using site as public user) both ‘search full text or ‘search by value’ did not work.
When I was logged-in the search by value did work, but search full text did not (as you pointed out)
I have since made the ‘extracted text’ as public. Now ‘search full text’ and ‘search by value’ both get results.
*extract text making the page so long. Basically I wanted to make the extracted text hidden instead of private. Or instead of hidden at least display it below all other properties including the Universal Viewer, on the Item page. I imagine this would be the preference of most users so if anyone has tips on how theyve done this i would be keen to hear! I don’t know if it can be done using Blocks Disposition or if it requires CSS editing
