Hello Baris,

Check out the filter factory and the map parser for a more low level example:

https://github.com/apache/lucene-solr/blob/master/lucene/analysis/common/src/java/org/apache/lucene/analysis/synonym/SynonymGraphFilterFactory.java
https://github.com/apache/lucene-solr/blob/master/lucene/analysis/common/src/java/org/apache/lucene/analysis/synonym/SynonymMap.java

Hello Baris,

The expand parameter defaults to true, so you should not have to add both rules. If you are using Solr, you can easily check it in the analysis tab. If not, printing the resulting Query object works as well.

Regards,
Markus

Well, query object is defined for searcher and synonyms are handled at index time.
This is not with solr.

i will not add both but then
123 or abc will mean abc or 123
even one mapping is defined then, right?

Best
