--------------------------------
Attachment: SOLR-4813.patch
I posted the patch of bug fix and improvement. Please review it.
The improvement is following.
{quote}
If TokenizerFactory's parameter name is the same as SynonymFilterFactory's parameter name, you must add prefix "tokenizerFactory." to TokenizerFactory's parameter name.

> When I write SynonymFilterFactory' setting in schema.xml as follows, ...
> {code:xml}
> <analyzer>
> <tokenizer class="solr.NGramTokenizerFactory" maxGramSize="2" minGramSize="2"/>
> <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"
> tokenizerFactory="solr.NGramTokenizerFactory" maxGramSize="2" minGramSize="2"/>
> </analyzer>
> {code}
> IllegalArgumentException ("Unknown parameters") occurs.
> {noformat}
> Caused by: java.lang.IllegalArgumentException: Unknown parameters: {maxGramSize=2, minGramSize=2}
> at org.apache.lucene.analysis.synonym.FSTSynonymFilterFactory.<init>(FSTSynonymFilterFactory.java:71)
> at org.apache.lucene.analysis.synonym.SynonymFilterFactory.<init>(SynonymFilterFactory.java:50)
> ... 28 more
> {noformat}
> However TokenizerFactory's params should be set to loadTokenizerFactory method in [FST|Slow]SynonymFilterFactory. (ref. SOLR-2909)
> I think, the problem was caused by LUCENE-4877 ("Fix analyzer factories to throw exception when arguments are invalid") and SOLR-3402 ("Parse Version outside of Analysis Factories").
