scripted find and find again...

I suspect may of us on this list have coded their own Find and Find 
Again (or Find Next) commands.

Some may use the Livecode "find" command (find [form] textToFind [in 
field]), but I suspect most (as even the Dictionary entry for Find 
recommends this) use offset or matchText.. Either approach, using 
"Find"or using "offset: (or equivalent) let you do Forward searches 
without jumping through hoops.

Many typical applications (MS-Word for example) support searching in 
either direction, forward or backwards. It appears Livecode's language 
has no support for Backwards searching. I found this positively ancient 
enhancement request:

https://quality.livecode.com/show_bug.cgi?id=946 (from 2003!!!)

So, I have the following questions:

1) Has anyone scripted  text search (of a field or variable content)  
that support forward and backwards searching?

1.1) As the equivalent of Find and Find Again

1.2) With hints, so it shows you snippets of the matches for you to jump 
to one rather then advancing sequentially through them?

2) I know the mother ship does not generally comment about future 
features, bit is any enhancement to scripted searching planned for 
LiveCode 10 or soon after?
