Hi again
i tried to add Synonyms in dictionary, for single part words like “test=>exam” it works fine but for more than one part words with spaces like “online test=>exam” it doesn’t work.
the line for this rule in the “synonym.txt” is:
online exam,online test=>exam

did i do something wrong ?

If you use standard tokenizer and synonym token filter, standard tokenizer is divides “online test” into online and test. So, “online test” does not match in synonym token filter.
I think it works if using ngram_synonym tokenizer .

Did you re-create fess index?

Hmm…
This is not Fess problem.
To solve it, I think that enough knowledge for Lucene analysis is needed…
