All:

I want to do a multi-word synonym search, to get search to work like:

"small dog" means puppy 
"cute small cat" may refer to kitten

[1] I do not know how to define those multi-word phrase in synonyms.txt to make it work. Could anyone ell me how to define those phrase in synonyms.txt

[2] Another thing is: Once the synonym can work, how can I match both "small dog" and "little dog" which have similar meaning with puppy? Like:

"a small dog" also means "small dog" means puppy 
"cute cat" may refer to "cute small cat" may refer to kitten

( I mean if there is any way we can collapse the phrase which has similar meaning and words into the synonym phrase which is in the synonym list)

Thanks

It could be done very easily.

In synonyms file you need to write something like this:

small dog => puppy

According to second question:

a small dog => puppy
little dog => puppy

=> in Solr synonyms file means 1-way synonym, if you want to to have 2-way synonyms, you need to list them with comma as a delimeter.
