Yes, thanks, I've tried it but from what I undestand it doesn't solve my problem, since this means hotel de ville will be replace by mairie at index time (I use synonyms only at index time). So when user will ask "hôtel de ville", it won't match. In fact, at index time I have mairie in my data, but I want user to be able to request "mairie" or "hôtel de ville" and have mairie as answer, and not have mairie as an answer when requesting "hôtel". <<To map `mairie` to `hotel de ville` as single token you must escape your white <<space. <<mairie, hotel\ de\ ville <<This results in a problem if your tokenizer splits on white space at query <<time. Ok, I guess this means I have a problem. No simple solution since at query time my tokenizer do split on white spaces. I guess my problem is more or less one of the problems discussed in http://lucene.472066.n3.nabble.com/Multi-word-synonyms-td3716292.html#a3717215 Thanks a lot for your answers, Elisabeth 2012/4/10 Erick Erickson <erickerick...@gmail.com> > Have you tried the "=>' mapping instead?
