Hi BaseX team!

I have a database with a text-index for a node named "serial-number"

with 2,164,980 occurrences of text '0000000'. [1]

...

If I execute :

util:item(db:text("US02", "0000000"), 1)

I get '0000000', as expected.

But, If I execute:

util:item(db:text("US02", "0000000"), 2)

I get the error message in [2]

The same happens with

db:text("US02", "0000000")[2]

subsequence(db:text("US02", "0000000"),2,1)

I recorded everything on this video [3]

Is this a bug?, I optimized the database before executing the queries.

Best regards, Sebastian.
