[andres]

Hi All,

Does setting 'facet.missing' to 'true' have any performance impact?

Performance Question: 'facets.missing'

[andres]

I'm debating whether or not to set the 'facets.missing' parameter to true by
default when faceting. What is the performance impact of setting
'facets.missing' to true?

synonyms

Hello everbody,

I have a doubt with respect to synonyms in Solr, In our company  we are lookink 
for one solution to resolve synonyms from database and not from one text file 
like SynonymFilterFactory do it.

The idea is save all the synonyms in the database, indexing and  they will be 
ready to one query, but we haven't found one solution from database.

Another idea is create one plugin that extend to SynonymFilterFactory but I 
don't know if this is posible.

I hope someone can help me.

regards,

RE: synonyms

Thanks for your answers, now I have another cuestions,if I develop the
filter to replacement the current synonym filter,I understand that this
procces would be in time of the indexing because in time of the query search
there are a lot problems knows. if so, how can I do for create my  index
file.

For example:
I have two synonyms "Nou cam", "Cataluña"  for  barcelona  in the data base


Opcion 1)
In time of the indexing would create 2 records like this:


   barcelona
   Camp Nou
...


and


   barcelona
   Cataluña
...


Opcion 2)

or only would create  one record like this:


   barcelona
   Camp Nou,Cataluña
...



If it create the opcion 2 can looking for by Camp Nou y by Cataluña but when
I looking for by barcelona the Solr return 2 records and that is one error
because barcelona is only one

IF it create the opcion 2 , I have searching wiht wildcards for example *Camp 
Nou* o *Cataluña* y the solr would return one records, the same case if 
searching by barcelona solr would return one recors that is good , but i want 
to know if is the better option or solr have another caracteristic betters  
that can resolve this topic of one better way.
