Does anyone know if it exists a viable alternative to make it configurable inside the schema.xml instead of defining a custom Java class? I was thinking about something like: * defining the *analyzer* outside of the *field* element, giving it a name: <analyzer name="myAnalyzer"> <tokenizer class="MyTokenizer" /> <filter class="solr.LowerCaseFilterFactory"/> <filter class="MyFilter_1" /> </analyzer> * referring to it inside the *SynonymFilter* definition by its name: <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true" analyzer="myAnalyzer"/> Unfortunately I have not found anything like this inside the Solr documentation. Is it possible to achieve something like that or the only solution is writing a custom Java class for each combination filter I need to use for synonyms analysis? Thanks.
