Subject Re: Derive suggestions across multiple fields
Date Wed, 03 Jun 2015 03:07:36 GMT
Thank you for your explanation.

I'll not need to care where the suggestions are coming from. All the
suggestions from different fields can be consolidate and display together.

I've tried to put those field into a new Suggestion copy field, but no
suggestion is shown when I set:
<str name="field">Suggestion</str>  <!-- the indexed field to derive
suggestions from -->

Is there a need to re-index the documents in order for this to work?

Regards,
Edwin
