SynonymGraphFilter can't consume an incoming graph

2019-02-10 Thread lambda.coder lucene
Hello,

The Javadocs of SynonymGraphFilter says that it can’t consume an incoming graph 
and that the result will be undefined

Is there any example that exhibits the limitations and what is meant by 
undefined ?


Regards
Patrick

Thanks Eric for your response

So I guess the answer to Shawn Heisey’s question [1] :

"Since multiple Graph filters cannot be used in an analysis chain, what is 
somebody running 8.0 supposed to do if they need both the WordDelimiter filter 
and Synonym filter in their analysis chain? »

is to have an analysis chain for the WordDelimiterGraphFilter and another one 
for the SynonymGraphFiler and then querying the two corresponding fields at the 
same time

There is currently no better option / alternative 

Am I right ?

Kind regards
Patrick
