Multi-word query time synonyms in elasticsearch.

# index the test documents
curl -XPUT 'http://localhost:9200/syns/test/1?pretty' -d '{"text": "the adventures of spiderman"}'
curl -XPUT 'http://localhost:9200/syns/test/2?pretty' -d '{"text": "what hath man wrought?"}'
curl -XPUT 'http://localhost:9200/syns/test/3?pretty&refresh=true' -d '{"text": "spiders eat insects"}'


# working query, finds correct document #1
curl -XPOST 'http://localhost:9200/syns/test/_search?pretty' -d '{"query": {"match": {"text": "spider man"}}}'

I know it's been a while, but for others that end up here searching: this only works because @mattweber used contraction on his synonym.

If a document were to contain the words spider and man, such as:

curl -XPUT 'http://localhost:9200/multiwordsyns/test/3?pretty' -d '{
    "text": "that spider is the size of a man"
}'

It would not be found by the query "spider man".

I've created another gist, based on this one, that expands on this issue a little: https://gist.github.com/ianribas/f76d20c21bb9f5c0df2f
