I have looked at all the posts and documentation but perhaps I missed the answer I would like answering.

How do I search for 'intransit' OR 'in-transit'
(some documents I have use both interchangeably)

Are there any special characters needed (PS I did try the '|' symbol between my 2 words)

Thank you

I created 2 new *.docx documents on my desktop.
Document 1 contained the single word 'In-transit'
Document 2 contained the singe word 'Intransit'

(Note: Capital 'I' in both cases)

I started FileSeek V1.7.1 and tried to search for:
*.doc*
intransit|in-transit

(Regular Expression Query was ticked)

The results were:
0 matches found 2 files searched.

So I didn't get a match.
