Hi Christian,

Thank you very much for your answer.

You were right: I've added a field named "GoodsServicesDescription" into full-index text and that was the cause of the error.

I removed it and the full-index now is created like a charm.

And yes: searching by that field is not a requirement for now.

BTW, we are evaluating BaseX to work with the UKIPO trademarks database ( several millions of records ), and so far it looks amazing.

I'll let you know how it goes.

Grüße aus dem Land der Gauchos nach Deutschland!

Sebastian.

Hi Sebastian,

I am afraid the input size seems to be too large for a full-text
index. I will check if we can improve the error feedback (usually, you
should get an info message that indicates that your data exceeds the
maximum size for an index instance).

If you don’t plan to query all texts of your document, you can reduce
memory consumption by restricting your index to specific elements (see
[1] for more information).

Did you successfully manage to create your database without full-text index?

Saludos (y buena salud) a Argentina,
Christian
