Concordance search does not recognise minimally different terms

Question

I've recently had this problem that almost identical terms are not being recognised in the concordance search. For example when the source text contains the (wrongly hyphenated) 
 "autism spec- trum disorder", the concordance search will say "no matches found" even though the TM contains many instances of "autism spectrum disorder". Is there anything I need to change in the setting?

Hi Gerti, I tested this and get this: 
 
 Perhaps you just need to reduce you search settings as the default is 70%, so it would not show this result unless you lower it. Go to Project Settings -> Language Pairs -> All Language Pairs - > TM and AT -> Search and you can reduce lookup and/or concordance.
