Using several Lucene analyzers

Hi,

I would want to use several Lucene analyzers. But when adding several analyzers in a new field type of an index repository, only one analyzer is kept after saving the index. 

See proof here: https://watch.screencastify.com/v/jvkgTLOEclM9YCgkVlbH

What is the roundabout? I may create several field types (one for each analyzer), create the corresponding index fields, and the a "Summary" field comprising the index fields, but I think is quite intrincated. Is there any simpler solution?

Regards,
Tomas

Hi Tomas

Yeah - I can see the UI issue. But it does not make sense to have more than one analyzer at a time.... I will create a bug to remove that part of the UI.

Hi Nicolai,

Ok with the bug. But then, how to use several analyzers? For instance, I need to use the UnaccentedWordAnalyzers (for Spanish) besides the SnowballAnalizer (for stem words) and SynonymAnalyzer (for synonyms).

Regards,
Tomas

You cannot - it does not make sense... An analyser tokenizes and creates terms from the input string - doing that 2 times makes no sense.

What are you trying to achieve?

I need to remove the accents, the plurals and include the synonyms. There are analyzers for each of this task, but no one that includes all.
