Using search regex fails when the fieldname is a number

[nnachefski]

So i have this regex:

| regex sy="\S{4,10}"

which works fine. I'm telling it to match only on non-whitespace characters 4 to 10 chars in length.

But, when i change the fieldname to a number the regex fails every time.

| regex 1="\S{4,10}"

I tried the following with no luck:

| regex "1"="\S{4,10}"

| regex "1=\S{4,10}"

Any help would be greatly appreciated.

Field names cannot begin with a number, so "1" is not a valid field name.
