Hi paul,

What kind of your document and query, you fail to search?

I think that “fui” and “jkt” synonym entries does not work, because “Florida International University” and “JKTyres” include UpperCase character.  
Your filter chain has the synonym filter after the lowercase filter.  
Your document data indexed all lowercase terms by your analyzer, but your query (ex: “jkt") expand “jkt” OR “JKTyres” by synonym filter.

However, I don’t know why “mlt” entry does not work, because “mit” entry is all lowercase character.

Does it make sense?

Regards,

Hi Jun,  
Adding "ignore\_case":true worked and for the "mit" there was some special  
character between words a double space or something mit, mass marked in red when  
i changed it to no space it worked. is there a specific format  
for synonym file and what should be the character encoding.
