slash in query not returning results "i/o"

[jgdoke]

We have many product names that have the slash as part of it.
Armor I/O, ArmorPoint I/O, ArmorBlock I/O, Awards
POINT I/O, POINT I/O Modules, FLEX I/O, FLEX I/O 16-point, FLEX I/O 32-point, Embedded I/O Cards, Distributed I/O

Customers are searching for it "distributed i/o". This does work. It is a problem if they only enter "i/o" returns "no documents found"

Similar issue with "plc 5/250" it works, but 5/250 returns no results.

You should add / to the Word Definition in all walk settings.

Sorry I do not understand a reg expression.
The current one is:
[\alnum\x80-\xff]{1,70}
[\alnum\x80-\xff.]{1,70}>>[.&']=[\alnum\x80-\xff.]{1,70}

How would I change it to include the slash?

Thanks

If you want a search for 250 to find 5/250 then add

[\alnum/\x80-\xff]{1,70}

to the expressions. If not replace

[\alnum\x80-\xff]{1,70}

with the above.
